Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656268, here are decompositions:

37 + 8656231 = 8656268
79 + 8656189 = 8656268
97 + 8656171 = 8656268
109 + 8656159 = 8656268
139 + 8656129 = 8656268
151 + 8656117 = 8656268
199 + 8656069 = 8656268
211 + 8656057 = 8656268

Showing the first eight; more decompositions exist.
