Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645304, here are decompositions:

11 + 8645293 = 8645304
23 + 8645281 = 8645304
37 + 8645267 = 8645304
43 + 8645261 = 8645304
47 + 8645257 = 8645304
61 + 8645243 = 8645304
67 + 8645237 = 8645304
163 + 8645141 = 8645304

Showing the first eight; more decompositions exist.
