Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656344, here are decompositions:

5 + 8656339 = 8656344
23 + 8656321 = 8656344
31 + 8656313 = 8656344
61 + 8656283 = 8656344
71 + 8656273 = 8656344
113 + 8656231 = 8656344
167 + 8656177 = 8656344
173 + 8656171 = 8656344

Showing the first eight; more decompositions exist.
