Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645306, here are decompositions:

13 + 8645293 = 8645306
37 + 8645269 = 8645306
67 + 8645239 = 8645306
127 + 8645179 = 8645306
193 + 8645113 = 8645306
277 + 8645029 = 8645306
283 + 8645023 = 8645306
349 + 8644957 = 8645306

Showing the first eight; more decompositions exist.
