Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509156, here are decompositions:

7 + 509149 = 509156
19 + 509137 = 509156
103 + 509053 = 509156
199 + 508957 = 509156
367 + 508789 = 509156
463 + 508693 = 509156
577 + 508579 = 509156
607 + 508549 = 509156

Showing the first eight; more decompositions exist.
