Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651272, here are decompositions:

5 + 8651267 = 8651272
11 + 8651261 = 8651272
41 + 8651231 = 8651272
83 + 8651189 = 8651272
131 + 8651141 = 8651272
233 + 8651039 = 8651272
263 + 8651009 = 8651272
293 + 8650979 = 8651272

Showing the first eight; more decompositions exist.
