Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678990, here are decompositions:

43 + 8678947 = 8678990
97 + 8678893 = 8678990
127 + 8678863 = 8678990
139 + 8678851 = 8678990
157 + 8678833 = 8678990
211 + 8678779 = 8678990
241 + 8678749 = 8678990
277 + 8678713 = 8678990

Showing the first eight; more decompositions exist.
