Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509090, here are decompositions:

3 + 509087 = 509090
19 + 509071 = 509090
37 + 509053 = 509090
67 + 509023 = 509090
103 + 508987 = 509090
139 + 508951 = 509090
181 + 508909 = 509090
223 + 508867 = 509090

Showing the first eight; more decompositions exist.
