This is not an equation, just an expression for a huge prime. An equation has an equals sign.

For instance, 2^{x}-1=15. That is an equation.

My TI-92 gave it to me, but it's too big to type out. It has about 385 digits.

The first 30 are 104079321946643990192524032736...

A calculator like a TI-89, TI-92, Voyage 200 will give it to you. Maple certanily will.
