Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507638, here are decompositions:

7 + 507631 = 507638
31 + 507607 = 507638
67 + 507571 = 507638
139 + 507499 = 507638
277 + 507361 = 507638
337 + 507301 = 507638
349 + 507289 = 507638
421 + 507217 = 507638

Showing the first eight; more decompositions exist.
