Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656394, here are decompositions:

31 + 8656363 = 8656394
37 + 8656357 = 8656394
73 + 8656321 = 8656394
163 + 8656231 = 8656394
223 + 8656171 = 8656394
277 + 8656117 = 8656394
337 + 8656057 = 8656394
457 + 8655937 = 8656394

Showing the first eight; more decompositions exist.
