Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651364, here are decompositions:

5 + 8651359 = 8651364
11 + 8651353 = 8651364
41 + 8651323 = 8651364
53 + 8651311 = 8651364
67 + 8651297 = 8651364
83 + 8651281 = 8651364
97 + 8651267 = 8651364
103 + 8651261 = 8651364

Showing the first eight; more decompositions exist.
