Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678822, here are decompositions:

43 + 8678779 = 8678822
73 + 8678749 = 8678822
109 + 8678713 = 8678822
151 + 8678671 = 8678822
223 + 8678599 = 8678822
241 + 8678581 = 8678822
349 + 8678473 = 8678822
463 + 8678359 = 8678822

Showing the first eight; more decompositions exist.
