Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688406, here are decompositions:

53 + 8688353 = 8688406
107 + 8688299 = 8688406
197 + 8688209 = 8688406
239 + 8688167 = 8688406
263 + 8688143 = 8688406
347 + 8688059 = 8688406
443 + 8687963 = 8688406
647 + 8687759 = 8688406

Showing the first eight; more decompositions exist.
