Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645418, here are decompositions:

11 + 8645407 = 8645418
37 + 8645381 = 8645418
59 + 8645359 = 8645418
137 + 8645281 = 8645418
149 + 8645269 = 8645418
151 + 8645267 = 8645418
157 + 8645261 = 8645418
179 + 8645239 = 8645418

Showing the first eight; more decompositions exist.
