Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712732, here are decompositions:

5 + 8712727 = 8712732
19 + 8712713 = 8712732
23 + 8712709 = 8712732
31 + 8712701 = 8712732
71 + 8712661 = 8712732
103 + 8712629 = 8712732
131 + 8712601 = 8712732
199 + 8712533 = 8712732

Showing the first eight; more decompositions exist.
