Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678636, here are decompositions:

37 + 8678599 = 8678636
79 + 8678557 = 8678636
163 + 8678473 = 8678636
277 + 8678359 = 8678636
283 + 8678353 = 8678636
313 + 8678323 = 8678636
433 + 8678203 = 8678636
457 + 8678179 = 8678636

Showing the first eight; more decompositions exist.
