Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651268, here are decompositions:

7 + 8651261 = 8651268
29 + 8651239 = 8651268
37 + 8651231 = 8651268
61 + 8651207 = 8651268
79 + 8651189 = 8651268
89 + 8651179 = 8651268
107 + 8651161 = 8651268
127 + 8651141 = 8651268

Showing the first eight; more decompositions exist.
