I don't think you misunderstood. 8 is a sum of 3 and 5, which are prime numbers. The conjecture is that all even numbers greater than 4 is a sum of two prime numbers (not necessarily the same or different). As far as I know, this conjecture is not proven though and thus shouldn't be considered a theorem. > Ok, let's see. > > 3x2=6 > But what about 8? It's factors are 1 and 8 and 2 and 4.
