Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648256, here are decompositions:

5 + 8648251 = 8648256
17 + 8648239 = 8648256
107 + 8648149 = 8648256
157 + 8648099 = 8648256
163 + 8648093 = 8648256
173 + 8648083 = 8648256
223 + 8648033 = 8648256
263 + 8647993 = 8648256

Showing the first eight; more decompositions exist.
