Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678866, here are decompositions:

3 + 8678863 = 8678866
83 + 8678783 = 8678866
89 + 8678777 = 8678866
107 + 8678759 = 8678866
113 + 8678753 = 8678866
167 + 8678699 = 8678866
173 + 8678693 = 8678866
197 + 8678669 = 8678866

Showing the first eight; more decompositions exist.
