What it means

Suppose you had a complete list of primes. Multiply them all together and add one. The result leaves a remainder of one when divided by every prime on your list, so either it is prime itself or it has a prime factor you missed. Either way the list was incomplete. The proof is over two thousand years old and has never needed patching.

The claim comes from Wolfram MathWorld.
