Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645358, here are decompositions:

5 + 8645353 = 8645358
17 + 8645341 = 8645358
31 + 8645327 = 8645358
89 + 8645269 = 8645358
97 + 8645261 = 8645358
101 + 8645257 = 8645358
179 + 8645179 = 8645358
277 + 8645081 = 8645358

Showing the first eight; more decompositions exist.
