Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651218, here are decompositions:

11 + 8651207 = 8651218
29 + 8651189 = 8651218
101 + 8651117 = 8651218
167 + 8651051 = 8651218
179 + 8651039 = 8651218
239 + 8650979 = 8651218
419 + 8650799 = 8651218
491 + 8650727 = 8651218

Showing the first eight; more decompositions exist.
