Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508478, here are decompositions:

7 + 508471 = 508478
151 + 508327 = 508478
181 + 508297 = 508478
241 + 508237 = 508478
307 + 508171 = 508478
349 + 508129 = 508478
457 + 508021 = 508478
499 + 507979 = 508478

Showing the first eight; more decompositions exist.
