Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645274, here are decompositions:

5 + 8645269 = 8645274
7 + 8645267 = 8645274
13 + 8645261 = 8645274
17 + 8645257 = 8645274
31 + 8645243 = 8645274
37 + 8645237 = 8645274
151 + 8645123 = 8645274
193 + 8645081 = 8645274

Showing the first eight; more decompositions exist.
