Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678622, here are decompositions:

19 + 8678603 = 8678622
23 + 8678599 = 8678622
41 + 8678581 = 8678622
103 + 8678519 = 8678622
149 + 8678473 = 8678622
223 + 8678399 = 8678622
229 + 8678393 = 8678622
263 + 8678359 = 8678622

Showing the first eight; more decompositions exist.
