Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634646, here are decompositions:

17 + 8634629 = 8634646
29 + 8634617 = 8634646
89 + 8634557 = 8634646
107 + 8634539 = 8634646
149 + 8634497 = 8634646
179 + 8634467 = 8634646
197 + 8634449 = 8634646
233 + 8634413 = 8634646

Showing the first eight; more decompositions exist.
