Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656364, here are decompositions:

7 + 8656357 = 8656364
43 + 8656321 = 8656364
193 + 8656171 = 8656364
271 + 8656093 = 8656364
307 + 8656057 = 8656364
331 + 8656033 = 8656364
373 + 8655991 = 8656364
397 + 8655967 = 8656364

Showing the first eight; more decompositions exist.
