Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639156, here are decompositions:

3 + 8639153 = 8639156
7 + 8639149 = 8639156
13 + 8639143 = 8639156
37 + 8639119 = 8639156
67 + 8639089 = 8639156
157 + 8638999 = 8639156
223 + 8638933 = 8639156
307 + 8638849 = 8639156

Showing the first eight; more decompositions exist.
