Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509158, here are decompositions:

11 + 509147 = 509158
71 + 509087 = 509158
131 + 509027 = 509158
197 + 508961 = 509158
227 + 508931 = 509158
239 + 508919 = 509158
257 + 508901 = 509158
311 + 508847 = 509158

Showing the first eight; more decompositions exist.
