Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712816, here are decompositions:

23 + 8712793 = 8712816
37 + 8712779 = 8712816
59 + 8712757 = 8712816
67 + 8712749 = 8712816
89 + 8712727 = 8712816
103 + 8712713 = 8712816
107 + 8712709 = 8712816
139 + 8712677 = 8712816

Showing the first eight; more decompositions exist.
