Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634784, here are decompositions:

17 + 8634767 = 8634784
23 + 8634761 = 8634784
71 + 8634713 = 8634784
107 + 8634677 = 8634784
113 + 8634671 = 8634784
167 + 8634617 = 8634784
227 + 8634557 = 8634784
233 + 8634551 = 8634784

Showing the first eight; more decompositions exist.
