Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634666, here are decompositions:

37 + 8634629 = 8634666
109 + 8634557 = 8634666
127 + 8634539 = 8634666
149 + 8634517 = 8634666
163 + 8634503 = 8634666
197 + 8634469 = 8634666
199 + 8634467 = 8634666
239 + 8634427 = 8634666

Showing the first eight; more decompositions exist.
