Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656328, here are decompositions:

7 + 8656321 = 8656328
97 + 8656231 = 8656328
139 + 8656189 = 8656328
151 + 8656177 = 8656328
157 + 8656171 = 8656328
181 + 8656147 = 8656328
199 + 8656129 = 8656328
211 + 8656117 = 8656328

Showing the first eight; more decompositions exist.
