Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678618, here are decompositions:

19 + 8678599 = 8678618
31 + 8678587 = 8678618
37 + 8678581 = 8678618
61 + 8678557 = 8678618
307 + 8678311 = 8678618
439 + 8678179 = 8678618
457 + 8678161 = 8678618
607 + 8678011 = 8678618

Showing the first eight; more decompositions exist.
