Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509138, here are decompositions:

37 + 509101 = 509138
67 + 509071 = 509138
151 + 508987 = 509138
181 + 508957 = 509138
229 + 508909 = 509138
271 + 508867 = 509138
349 + 508789 = 509138
367 + 508771 = 509138

Showing the first eight; more decompositions exist.
