Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645256, here are decompositions:

13 + 8645243 = 8645256
17 + 8645239 = 8645256
19 + 8645237 = 8645256
227 + 8645029 = 8645256
233 + 8645023 = 8645256
293 + 8644963 = 8645256
307 + 8644949 = 8645256
337 + 8644919 = 8645256

Showing the first eight; more decompositions exist.
