Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616646, here are decompositions:

47 + 8616599 = 8616646
83 + 8616563 = 8616646
113 + 8616533 = 8616646
239 + 8616407 = 8616646
293 + 8616353 = 8616646
347 + 8616299 = 8616646
443 + 8616203 = 8616646
449 + 8616197 = 8616646

Showing the first eight; more decompositions exist.
