Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678992, here are decompositions:

29 + 8678963 = 8678992
41 + 8678951 = 8678992
53 + 8678939 = 8678992
59 + 8678933 = 8678992
89 + 8678903 = 8678992
233 + 8678759 = 8678992
239 + 8678753 = 8678992
251 + 8678741 = 8678992

Showing the first eight; more decompositions exist.
