Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508656, here are decompositions:

13 + 508643 = 508656
19 + 508637 = 508656
37 + 508619 = 508656
73 + 508583 = 508656
79 + 508577 = 508656
89 + 508567 = 508656
97 + 508559 = 508656
107 + 508549 = 508656

Showing the first eight; more decompositions exist.
