Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509718, here are decompositions:

19 + 509699 = 509718
29 + 509689 = 509718
31 + 509687 = 509718
37 + 509681 = 509718
59 + 509659 = 509718
71 + 509647 = 509718
127 + 509591 = 509718
137 + 509581 = 509718

Showing the first eight; more decompositions exist.
