First of all, I stand corrected on my comment about uniqueness in the conjecture. I remember there was something like that, maybe it was that there are always at least two DISTINCT primes for n where n>4 and n is even. So although 10 is 5 and 5, it can also be arrived at with two distinct primes,

Ah, this is more fun than complaints about network administration ... Goldbach's Conjecture states that every even number greater than 4 is the sum of two primes. It hasn't been proved yet; the closest we've got is a result by Chen using sieve theory which shows that every sufficiently large even
