Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651474, here are decompositions:

31 + 8651443 = 8651474
37 + 8651437 = 8651474
151 + 8651323 = 8651474
163 + 8651311 = 8651474
193 + 8651281 = 8651474
241 + 8651233 = 8651474
283 + 8651191 = 8651474
313 + 8651161 = 8651474

Showing the first eight; more decompositions exist.
