Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628678, here are decompositions:

17 + 8628661 = 8628678
31 + 8628647 = 8628678
127 + 8628551 = 8628678
131 + 8628547 = 8628678
197 + 8628481 = 8628678
199 + 8628479 = 8628678
229 + 8628449 = 8628678
257 + 8628421 = 8628678

Showing the first eight; more decompositions exist.
