Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651278, here are decompositions:

11 + 8651267 = 8651278
17 + 8651261 = 8651278
47 + 8651231 = 8651278
71 + 8651207 = 8651278
89 + 8651189 = 8651278
137 + 8651141 = 8651278
227 + 8651051 = 8651278
239 + 8651039 = 8651278

Showing the first eight; more decompositions exist.
