Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712736, here are decompositions:

23 + 8712713 = 8712736
59 + 8712677 = 8712736
107 + 8712629 = 8712736
239 + 8712497 = 8712736
443 + 8712293 = 8712736
449 + 8712287 = 8712736
467 + 8712269 = 8712736
479 + 8712257 = 8712736

Showing the first eight; more decompositions exist.
