Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668646, here are decompositions:

3 + 8668643 = 8668646
37 + 8668609 = 8668646
97 + 8668549 = 8668646
127 + 8668519 = 8668646
157 + 8668489 = 8668646
163 + 8668483 = 8668646
223 + 8668423 = 8668646
277 + 8668369 = 8668646

Showing the first eight; more decompositions exist.
