Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508628, here are decompositions:

7 + 508621 = 508628
61 + 508567 = 508628
79 + 508549 = 508628
97 + 508531 = 508628
139 + 508489 = 508628
151 + 508477 = 508628
157 + 508471 = 508628
331 + 508297 = 508628

Showing the first eight; more decompositions exist.
