Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8633646, here are decompositions:

5 + 8633641 = 8633646
13 + 8633633 = 8633646
79 + 8633567 = 8633646
157 + 8633489 = 8633646
193 + 8633453 = 8633646
223 + 8633423 = 8633646
233 + 8633413 = 8633646
257 + 8633389 = 8633646

Showing the first eight; more decompositions exist.
