Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641634, here are decompositions:

3 + 8641631 = 8641634
13 + 8641621 = 8641634
31 + 8641603 = 8641634
163 + 8641471 = 8641634
181 + 8641453 = 8641634
283 + 8641351 = 8641634
307 + 8641327 = 8641634
487 + 8641147 = 8641634

Showing the first eight; more decompositions exist.
