Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513684, here are decompositions:

5 + 513679 = 513684
11 + 513673 = 513684
43 + 513641 = 513684
53 + 513631 = 513684
151 + 513533 = 513684
173 + 513511 = 513684
211 + 513473 = 513684
257 + 513427 = 513684

Showing the first eight; more decompositions exist.
