Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712784, here are decompositions:

5 + 8712779 = 8712784
23 + 8712761 = 8712784
71 + 8712713 = 8712784
83 + 8712701 = 8712784
107 + 8712677 = 8712784
173 + 8712611 = 8712784
251 + 8712533 = 8712784
293 + 8712491 = 8712784

Showing the first eight; more decompositions exist.
