Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509666, here are decompositions:

7 + 509659 = 509666
13 + 509653 = 509666
19 + 509647 = 509666
43 + 509623 = 509666
97 + 509569 = 509666
103 + 509563 = 509666
109 + 509557 = 509666
277 + 509389 = 509666

Showing the first eight; more decompositions exist.
