Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646680, here are decompositions:

13 + 8646667 = 8646680
73 + 8646607 = 8646680
109 + 8646571 = 8646680
151 + 8646529 = 8646680
193 + 8646487 = 8646680
223 + 8646457 = 8646680
277 + 8646403 = 8646680
421 + 8646259 = 8646680

Showing the first eight; more decompositions exist.
