Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656238, here are decompositions:

7 + 8656231 = 8656238
61 + 8656177 = 8656238
67 + 8656171 = 8656238
79 + 8656159 = 8656238
109 + 8656129 = 8656238
181 + 8656057 = 8656238
271 + 8655967 = 8656238
337 + 8655901 = 8656238

Showing the first eight; more decompositions exist.
