Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508638, here are decompositions:

17 + 508621 = 508638
19 + 508619 = 508638
59 + 508579 = 508638
61 + 508577 = 508638
71 + 508567 = 508638
79 + 508559 = 508638
89 + 508549 = 508638
107 + 508531 = 508638

Showing the first eight; more decompositions exist.
