Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651342, here are decompositions:

13 + 8651329 = 8651342
19 + 8651323 = 8651342
31 + 8651311 = 8651342
61 + 8651281 = 8651342
103 + 8651239 = 8651342
109 + 8651233 = 8651342
151 + 8651191 = 8651342
163 + 8651179 = 8651342

Showing the first eight; more decompositions exist.
