Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656646, here are decompositions:

43 + 8656603 = 8656646
73 + 8656573 = 8656646
109 + 8656537 = 8656646
223 + 8656423 = 8656646
277 + 8656369 = 8656646
283 + 8656363 = 8656646
307 + 8656339 = 8656646
367 + 8656279 = 8656646

Showing the first eight; more decompositions exist.
