Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678980, here are decompositions:

17 + 8678963 = 8678980
29 + 8678951 = 8678980
41 + 8678939 = 8678980
47 + 8678933 = 8678980
53 + 8678927 = 8678980
197 + 8678783 = 8678980
227 + 8678753 = 8678980
239 + 8678741 = 8678980

Showing the first eight; more decompositions exist.
