Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678616, here are decompositions:

13 + 8678603 = 8678616
17 + 8678599 = 8678616
29 + 8678587 = 8678616
59 + 8678557 = 8678616
97 + 8678519 = 8678616
109 + 8678507 = 8678616
223 + 8678393 = 8678616
257 + 8678359 = 8678616

Showing the first eight; more decompositions exist.
