Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656148, here are decompositions:

19 + 8656129 = 8656148
31 + 8656117 = 8656148
79 + 8656069 = 8656148
157 + 8655991 = 8656148
181 + 8655967 = 8656148
211 + 8655937 = 8656148
229 + 8655919 = 8656148
271 + 8655877 = 8656148

Showing the first eight; more decompositions exist.
