Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645336, here are decompositions:

43 + 8645293 = 8645336
67 + 8645269 = 8645336
79 + 8645257 = 8645336
97 + 8645239 = 8645336
157 + 8645179 = 8645336
223 + 8645113 = 8645336
283 + 8645053 = 8645336
307 + 8645029 = 8645336

Showing the first eight; more decompositions exist.
