Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656544, here are decompositions:

7 + 8656537 = 8656544
67 + 8656477 = 8656544
151 + 8656393 = 8656544
181 + 8656363 = 8656544
223 + 8656321 = 8656544
271 + 8656273 = 8656544
313 + 8656231 = 8656544
367 + 8656177 = 8656544

Showing the first eight; more decompositions exist.
