Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656726, here are decompositions:

5 + 8656721 = 8656726
59 + 8656667 = 8656726
137 + 8656589 = 8656726
149 + 8656577 = 8656726
179 + 8656547 = 8656726
227 + 8656499 = 8656726
233 + 8656493 = 8656726
257 + 8656469 = 8656726

Showing the first eight; more decompositions exist.
