Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8633664, here are decompositions:

5 + 8633659 = 8633664
23 + 8633641 = 8633664
31 + 8633633 = 8633664
97 + 8633567 = 8633664
113 + 8633551 = 8633664
211 + 8633453 = 8633664
233 + 8633431 = 8633664
241 + 8633423 = 8633664

Showing the first eight; more decompositions exist.
