Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656368, here are decompositions:

5 + 8656363 = 8656368
11 + 8656357 = 8656368
29 + 8656339 = 8656368
47 + 8656321 = 8656368
89 + 8656279 = 8656368
137 + 8656231 = 8656368
179 + 8656189 = 8656368
191 + 8656177 = 8656368

Showing the first eight; more decompositions exist.
