Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509518, here are decompositions:

5 + 509513 = 509518
41 + 509477 = 509518
89 + 509429 = 509518
101 + 509417 = 509518
431 + 509087 = 509518
491 + 509027 = 509518
557 + 508961 = 509518
587 + 508931 = 509518

Showing the first eight; more decompositions exist.
