Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651484, here are decompositions:

41 + 8651443 = 8651484
47 + 8651437 = 8651484
131 + 8651353 = 8651484
173 + 8651311 = 8651484
223 + 8651261 = 8651484
251 + 8651233 = 8651484
277 + 8651207 = 8651484
293 + 8651191 = 8651484

Showing the first eight; more decompositions exist.
