Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510938, here are decompositions:

7 + 510931 = 510938
19 + 510919 = 510938
31 + 510907 = 510938
229 + 510709 = 510938
349 + 510589 = 510938
409 + 510529 = 510938
457 + 510481 = 510938
487 + 510451 = 510938

Showing the first eight; more decompositions exist.
