Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656222, here are decompositions:

53 + 8656169 = 8656222
59 + 8656163 = 8656222
89 + 8656133 = 8656222
131 + 8656091 = 8656222
191 + 8656031 = 8656222
269 + 8655953 = 8656222
353 + 8655869 = 8656222
461 + 8655761 = 8656222

Showing the first eight; more decompositions exist.
