Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509318, here are decompositions:

31 + 509287 = 509318
37 + 509281 = 509318
79 + 509239 = 509318
97 + 509221 = 509318
181 + 509137 = 509318
331 + 508987 = 509318
349 + 508969 = 509318
367 + 508951 = 509318

Showing the first eight; more decompositions exist.
