Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647226, here are decompositions:

43 + 8647183 = 8647226
97 + 8647129 = 8647226
103 + 8647123 = 8647226
163 + 8647063 = 8647226
199 + 8647027 = 8647226
277 + 8646949 = 8647226
283 + 8646943 = 8647226
337 + 8646889 = 8647226

Showing the first eight; more decompositions exist.
