Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508658, here are decompositions:

37 + 508621 = 508658
79 + 508579 = 508658
109 + 508549 = 508658
127 + 508531 = 508658
181 + 508477 = 508658
331 + 508327 = 508658
421 + 508237 = 508658
487 + 508171 = 508658

Showing the first eight; more decompositions exist.
