Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651456, here are decompositions:

13 + 8651443 = 8651456
19 + 8651437 = 8651456
67 + 8651389 = 8651456
97 + 8651359 = 8651456
103 + 8651353 = 8651456
127 + 8651329 = 8651456
223 + 8651233 = 8651456
277 + 8651179 = 8651456

Showing the first eight; more decompositions exist.
