Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656260, here are decompositions:

7 + 8656253 = 8656260
29 + 8656231 = 8656260
71 + 8656189 = 8656260
83 + 8656177 = 8656260
89 + 8656171 = 8656260
97 + 8656163 = 8656260
101 + 8656159 = 8656260
113 + 8656147 = 8656260

Showing the first eight; more decompositions exist.
