Can't be done on several levels.
First, the center of Earth is totally inimical; nothing can survive there other than the molten mass that is already there. You'd be lucky (?) to get those warheads just a few miles deeps before all kinds of survivability issues would arise.
Second, there are not only not sufficient warheads now to equal the yield needed to split Earth asunder, there is not enough fissionable/fusible materiel on this planet to make the numbers needed for that yield.
Assume we split the planet in half. Without taking into account the work function required to overcome the gravitation attraction (f) of the two halves (that is we're just overcoming inertia), the impulse generate from the force (yield) of the warheads would push the two halves and accelerate them to some end speed V > 0. Once up to speed and discounting gravity, the two halves would continue on under their own momenta.
Using 1 MT = 8896443230.521 = 8.89E9 Newtons and Earth's mass as M = 5.97E24 kg, we assume dT = 10 seconds as the pulse interval of the massive explosion. So, to get the two halves to move at, say, V = 1 mps, we have (M/2)V = F dT and F = (5.97E24/2)*1/10 = 2.985E+23 N. or a nominal yield of Y = 2.98E23/8.89E9 = 3.35E+13 megatons. ANS.
That's 33.5 trillion 1 MT warheads and all the physics packages that go into them. As I indicated earlier, there are not enough on the entire planet to do the job. All together, with all of the warheads from all the nations, there probably less than 5,000 strategic weapons. So, as you can see, we fall well short of being able to rip Earth into two parts. And remember this 33.5 trillion MT is a minimal guess as we discounted the attraction forces of gravity on the two halves.
The numbers above are WAGs. But I'd guess they are representative of the orders of magnitude for the yield needed to tear the Earth apart. And those trillions can be reduced by orders of magnitude (e.g., a longer pulse like dT = 1000 seconds) and the numbers would still be unreachable to split the Earth.
