Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668722, here are decompositions:

11 + 8668711 = 8668722
79 + 8668643 = 8668722
109 + 8668613 = 8668722
113 + 8668609 = 8668722
151 + 8668571 = 8668722
173 + 8668549 = 8668722
199 + 8668523 = 8668722
233 + 8668489 = 8668722

Showing the first eight; more decompositions exist.
