Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706668, here are decompositions:

211 + 8706457 = 8706668
307 + 8706361 = 8706668
331 + 8706337 = 8706668
379 + 8706289 = 8706668
499 + 8706169 = 8706668
661 + 8706007 = 8706668
709 + 8705959 = 8706668
727 + 8705941 = 8706668

Showing the first eight; more decompositions exist.
