Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656224, here are decompositions:

47 + 8656177 = 8656224
53 + 8656171 = 8656224
61 + 8656163 = 8656224
107 + 8656117 = 8656224
127 + 8656097 = 8656224
131 + 8656093 = 8656224
167 + 8656057 = 8656224
191 + 8656033 = 8656224

Showing the first eight; more decompositions exist.
