Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649460, here are decompositions:

41 + 8649419 = 8649460
89 + 8649371 = 8649460
107 + 8649353 = 8649460
137 + 8649323 = 8649460
167 + 8649293 = 8649460
233 + 8649227 = 8649460
263 + 8649197 = 8649460
269 + 8649191 = 8649460

Showing the first eight; more decompositions exist.
