Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678816, here are decompositions:

37 + 8678779 = 8678816
43 + 8678773 = 8678816
67 + 8678749 = 8678816
103 + 8678713 = 8678816
109 + 8678707 = 8678816
229 + 8678587 = 8678816
457 + 8678359 = 8678816
463 + 8678353 = 8678816

Showing the first eight; more decompositions exist.
