Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651266, here are decompositions:

5 + 8651261 = 8651266
59 + 8651207 = 8651266
149 + 8651117 = 8651266
227 + 8651039 = 8651266
257 + 8651009 = 8651266
269 + 8650997 = 8651266
347 + 8650919 = 8651266
467 + 8650799 = 8651266

Showing the first eight; more decompositions exist.
