Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510506, here are decompositions:

43 + 510463 = 510506
103 + 510403 = 510506
127 + 510379 = 510506
307 + 510199 = 510506
349 + 510157 = 510506
379 + 510127 = 510506
433 + 510073 = 510506
439 + 510067 = 510506

Showing the first eight; more decompositions exist.
