Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645502, here are decompositions:

11 + 8645491 = 8645502
53 + 8645449 = 8645502
59 + 8645443 = 8645502
71 + 8645431 = 8645502
149 + 8645353 = 8645502
233 + 8645269 = 8645502
241 + 8645261 = 8645502
263 + 8645239 = 8645502

Showing the first eight; more decompositions exist.
