Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656272, here are decompositions:

19 + 8656253 = 8656272
41 + 8656231 = 8656272
83 + 8656189 = 8656272
101 + 8656171 = 8656272
103 + 8656169 = 8656272
109 + 8656163 = 8656272
113 + 8656159 = 8656272
139 + 8656133 = 8656272

Showing the first eight; more decompositions exist.
