Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508688, here are decompositions:

67 + 508621 = 508688
109 + 508579 = 508688
139 + 508549 = 508688
157 + 508531 = 508688
199 + 508489 = 508688
211 + 508477 = 508688
601 + 508087 = 508688
709 + 507979 = 508688

Showing the first eight; more decompositions exist.
