Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678864, here are decompositions:

13 + 8678851 = 8678864
31 + 8678833 = 8678864
43 + 8678821 = 8678864
151 + 8678713 = 8678864
157 + 8678707 = 8678864
163 + 8678701 = 8678864
193 + 8678671 = 8678864
277 + 8678587 = 8678864

Showing the first eight; more decompositions exist.
