Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678986, here are decompositions:

23 + 8678963 = 8678986
47 + 8678939 = 8678986
53 + 8678933 = 8678986
59 + 8678927 = 8678986
83 + 8678903 = 8678986
227 + 8678759 = 8678986
233 + 8678753 = 8678986
293 + 8678693 = 8678986

Showing the first eight; more decompositions exist.
