Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8633640, here are decompositions:

7 + 8633633 = 8633640
73 + 8633567 = 8633640
89 + 8633551 = 8633640
151 + 8633489 = 8633640
179 + 8633461 = 8633640
181 + 8633459 = 8633640
227 + 8633413 = 8633640
251 + 8633389 = 8633640

Showing the first eight; more decompositions exist.
