Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651366, here are decompositions:

7 + 8651359 = 8651366
13 + 8651353 = 8651366
37 + 8651329 = 8651366
43 + 8651323 = 8651366
127 + 8651239 = 8651366
223 + 8651143 = 8651366
349 + 8651017 = 8651366
439 + 8650927 = 8651366

Showing the first eight; more decompositions exist.
