Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510656, here are decompositions:

37 + 510619 = 510656
43 + 510613 = 510656
67 + 510589 = 510656
73 + 510583 = 510656
103 + 510553 = 510656
127 + 510529 = 510656
193 + 510463 = 510656
199 + 510457 = 510656

Showing the first eight; more decompositions exist.
