Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509128, here are decompositions:

5 + 509123 = 509128
41 + 509087 = 509128
101 + 509027 = 509128
167 + 508961 = 509128
197 + 508931 = 509128
227 + 508901 = 509128
281 + 508847 = 509128
311 + 508817 = 509128

Showing the first eight; more decompositions exist.
