Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646446, here are decompositions:

43 + 8646403 = 8646446
199 + 8646247 = 8646446
223 + 8646223 = 8646446
283 + 8646163 = 8646446
547 + 8645899 = 8646446
643 + 8645803 = 8646446
673 + 8645773 = 8646446
727 + 8645719 = 8646446

Showing the first eight; more decompositions exist.
