Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651360, here are decompositions:

7 + 8651353 = 8651360
31 + 8651329 = 8651360
37 + 8651323 = 8651360
79 + 8651281 = 8651360
127 + 8651233 = 8651360
181 + 8651179 = 8651360
199 + 8651161 = 8651360
241 + 8651119 = 8651360

Showing the first eight; more decompositions exist.
