Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509440, here are decompositions:

11 + 509429 = 509440
23 + 509417 = 509440
47 + 509393 = 509440
293 + 509147 = 509440
317 + 509123 = 509440
353 + 509087 = 509440
467 + 508973 = 509440
479 + 508961 = 509440

Showing the first eight; more decompositions exist.
