Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717512, here are decompositions:

3 + 8717509 = 8717512
239 + 8717273 = 8717512
311 + 8717201 = 8717512
389 + 8717123 = 8717512
491 + 8717021 = 8717512
569 + 8716943 = 8717512
593 + 8716919 = 8717512
659 + 8716853 = 8717512

Showing the first eight; more decompositions exist.
