Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510728, here are decompositions:

19 + 510709 = 510728
37 + 510691 = 510728
109 + 510619 = 510728
139 + 510589 = 510728
199 + 510529 = 510728
271 + 510457 = 510728
277 + 510451 = 510728
349 + 510379 = 510728

Showing the first eight; more decompositions exist.
