Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651450, here are decompositions:

7 + 8651443 = 8651450
13 + 8651437 = 8651450
61 + 8651389 = 8651450
97 + 8651353 = 8651450
127 + 8651323 = 8651450
139 + 8651311 = 8651450
211 + 8651239 = 8651450
271 + 8651179 = 8651450

Showing the first eight; more decompositions exist.
