Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645292, here are decompositions:

11 + 8645281 = 8645292
23 + 8645269 = 8645292
31 + 8645261 = 8645292
53 + 8645239 = 8645292
113 + 8645179 = 8645292
151 + 8645141 = 8645292
179 + 8645113 = 8645292
211 + 8645081 = 8645292

Showing the first eight; more decompositions exist.
