Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647646, here are decompositions:

67 + 8647579 = 8647646
79 + 8647567 = 8647646
109 + 8647537 = 8647646
199 + 8647447 = 8647646
229 + 8647417 = 8647646
277 + 8647369 = 8647646
373 + 8647273 = 8647646
463 + 8647183 = 8647646

Showing the first eight; more decompositions exist.
