I was wondering... since this competition has been over for quite some time, would it be ok for someone to explain to me the process for problem 2? I have no earthy idea how to begin solving it, as it implies we need to know the set of all primes (i.e. {P1,P2,...Pn}). I think it's an incredibly intriguing problem nonetheless!
