Fair enough. How about the problem of whether every even number greater than 2 is the sum of two primes? If I didn't know that was called the Goldbach conjecture, how would I find it?
Well, okay, Googling "sum of two primes" finds it. Never mind.
Or, compute the number of ways to write 4, 6, 8, ..., 20 as a sum of two primes, and enter this sequence into oeis.org. Jim Propp
