Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656256, here are decompositions:

3 + 8656253 = 8656256
67 + 8656189 = 8656256
79 + 8656177 = 8656256
97 + 8656159 = 8656256
109 + 8656147 = 8656256
127 + 8656129 = 8656256
139 + 8656117 = 8656256
163 + 8656093 = 8656256

Showing the first eight; more decompositions exist.
