Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519664, here are decompositions:

17 + 519647 = 519664
53 + 519611 = 519664
83 + 519581 = 519664
113 + 519551 = 519664
137 + 519527 = 519664
251 + 519413 = 519664
281 + 519383 = 519664
293 + 519371 = 519664

Showing the first eight; more decompositions exist.
