Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509140, here are decompositions:

3 + 509137 = 509140
17 + 509123 = 509140
53 + 509087 = 509140
113 + 509027 = 509140
167 + 508973 = 509140
179 + 508961 = 509140
197 + 508943 = 509140
227 + 508913 = 509140

Showing the first eight; more decompositions exist.
