Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646656, here are decompositions:

97 + 8646559 = 8646656
127 + 8646529 = 8646656
199 + 8646457 = 8646656
379 + 8646277 = 8646656
397 + 8646259 = 8646656
409 + 8646247 = 8646656
433 + 8646223 = 8646656
757 + 8645899 = 8646656

Showing the first eight; more decompositions exist.
