Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656278, here are decompositions:

5 + 8656273 = 8656278
47 + 8656231 = 8656278
89 + 8656189 = 8656278
101 + 8656177 = 8656278
107 + 8656171 = 8656278
109 + 8656169 = 8656278
131 + 8656147 = 8656278
149 + 8656129 = 8656278

Showing the first eight; more decompositions exist.
