Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509258, here are decompositions:

19 + 509239 = 509258
31 + 509227 = 509258
37 + 509221 = 509258
109 + 509149 = 509258
157 + 509101 = 509258
271 + 508987 = 509258
307 + 508951 = 509258
349 + 508909 = 509258

Showing the first eight; more decompositions exist.
