Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509758, here are decompositions:

17 + 509741 = 509758
59 + 509699 = 509758
71 + 509687 = 509758
167 + 509591 = 509758
281 + 509477 = 509758
317 + 509441 = 509758
461 + 509297 = 509758
797 + 508961 = 509758

Showing the first eight; more decompositions exist.
