Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508778, here are decompositions:

7 + 508771 = 508778
157 + 508621 = 508778
199 + 508579 = 508778
211 + 508567 = 508778
229 + 508549 = 508778
307 + 508471 = 508778
541 + 508237 = 508778
607 + 508171 = 508778

Showing the first eight; more decompositions exist.
