Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509188, here are decompositions:

41 + 509147 = 509188
101 + 509087 = 509188
227 + 508961 = 509188
257 + 508931 = 509188
269 + 508919 = 509188
347 + 508841 = 509188
389 + 508799 = 509188
461 + 508727 = 509188

Showing the first eight; more decompositions exist.
