Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656320, here are decompositions:

7 + 8656313 = 8656320
37 + 8656283 = 8656320
41 + 8656279 = 8656320
47 + 8656273 = 8656320
67 + 8656253 = 8656320
89 + 8656231 = 8656320
131 + 8656189 = 8656320
149 + 8656171 = 8656320

Showing the first eight; more decompositions exist.
