Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656340, here are decompositions:

19 + 8656321 = 8656340
61 + 8656279 = 8656340
67 + 8656273 = 8656340
109 + 8656231 = 8656340
151 + 8656189 = 8656340
163 + 8656177 = 8656340
181 + 8656159 = 8656340
193 + 8656147 = 8656340

Showing the first eight; more decompositions exist.
