Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651318, here are decompositions:

7 + 8651311 = 8651318
37 + 8651281 = 8651318
79 + 8651239 = 8651318
127 + 8651191 = 8651318
139 + 8651179 = 8651318
157 + 8651161 = 8651318
199 + 8651119 = 8651318
271 + 8651047 = 8651318

Showing the first eight; more decompositions exist.
