  1. If you use one of those programs that searches for primes during your computer’s idle time (similar to the SETI@home thing) and you unearth the 10m digit prime, do you get the prize, or does it go to the program makers?

  2. GIMPS would claim the prize and you would get half of it, the other half being distributed amongst previous prime discoverers. The full details can be found at Monetary Awards where it says that Your chance of success is roughly 1 in 250,000.
