Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656284, here are decompositions:

5 + 8656279 = 8656284
11 + 8656273 = 8656284
31 + 8656253 = 8656284
53 + 8656231 = 8656284
107 + 8656177 = 8656284
113 + 8656171 = 8656284
137 + 8656147 = 8656284
151 + 8656133 = 8656284

Showing the first eight; more decompositions exist.
