Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647406, here are decompositions:

13 + 8647393 = 8647406
37 + 8647369 = 8647406
223 + 8647183 = 8647406
277 + 8647129 = 8647406
283 + 8647123 = 8647406
379 + 8647027 = 8647406
457 + 8646949 = 8647406
463 + 8646943 = 8647406

Showing the first eight; more decompositions exist.
