Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509278, here are decompositions:

131 + 509147 = 509278
191 + 509087 = 509278
251 + 509027 = 509278
317 + 508961 = 509278
347 + 508931 = 509278
359 + 508919 = 509278
431 + 508847 = 509278
461 + 508817 = 509278

Showing the first eight; more decompositions exist.
