Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645286, here are decompositions:

5 + 8645281 = 8645286
17 + 8645269 = 8645286
19 + 8645267 = 8645286
29 + 8645257 = 8645286
43 + 8645243 = 8645286
47 + 8645239 = 8645286
107 + 8645179 = 8645286
163 + 8645123 = 8645286

Showing the first eight; more decompositions exist.
