Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508508, here are decompositions:

19 + 508489 = 508508
31 + 508477 = 508508
37 + 508471 = 508508
181 + 508327 = 508508
211 + 508297 = 508508
271 + 508237 = 508508
337 + 508171 = 508508
349 + 508159 = 508508

Showing the first eight; more decompositions exist.
