Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509684, here are decompositions:

3 + 509681 = 509684
31 + 509653 = 509684
37 + 509647 = 509684
61 + 509623 = 509684
103 + 509581 = 509684
127 + 509557 = 509684
163 + 509521 = 509684
271 + 509413 = 509684

Showing the first eight; more decompositions exist.
