Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678776, here are decompositions:

3 + 8678773 = 8678776
17 + 8678759 = 8678776
23 + 8678753 = 8678776
83 + 8678693 = 8678776
107 + 8678669 = 8678776
137 + 8678639 = 8678776
173 + 8678603 = 8678776
257 + 8678519 = 8678776

Showing the first eight; more decompositions exist.
