Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639256, here are decompositions:

5 + 8639251 = 8639256
7 + 8639249 = 8639256
29 + 8639227 = 8639256
37 + 8639219 = 8639256
79 + 8639177 = 8639256
103 + 8639153 = 8639256
107 + 8639149 = 8639256
113 + 8639143 = 8639256

Showing the first eight; more decompositions exist.
