Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509756, here are decompositions:

19 + 509737 = 509756
67 + 509689 = 509756
97 + 509659 = 509756
103 + 509653 = 509756
109 + 509647 = 509756
193 + 509563 = 509756
199 + 509557 = 509756
307 + 509449 = 509756

Showing the first eight; more decompositions exist.
