Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656286, here are decompositions:

3 + 8656283 = 8656286
7 + 8656279 = 8656286
13 + 8656273 = 8656286
97 + 8656189 = 8656286
109 + 8656177 = 8656286
127 + 8656159 = 8656286
139 + 8656147 = 8656286
157 + 8656129 = 8656286

Showing the first eight; more decompositions exist.
