Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718646, here are decompositions:

107 + 8718539 = 8718646
227 + 8718419 = 8718646
239 + 8718407 = 8718646
269 + 8718377 = 8718646
449 + 8718197 = 8718646
557 + 8718089 = 8718646
647 + 8717999 = 8718646
653 + 8717993 = 8718646

Showing the first eight; more decompositions exist.
