Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651316, here are decompositions:

5 + 8651311 = 8651316
19 + 8651297 = 8651316
83 + 8651233 = 8651316
109 + 8651207 = 8651316
127 + 8651189 = 8651316
137 + 8651179 = 8651316
173 + 8651143 = 8651316
197 + 8651119 = 8651316

Showing the first eight; more decompositions exist.
