Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8633638, here are decompositions:

5 + 8633633 = 8633638
71 + 8633567 = 8633638
149 + 8633489 = 8633638
179 + 8633459 = 8633638
257 + 8633381 = 8633638
311 + 8633327 = 8633638
359 + 8633279 = 8633638
401 + 8633237 = 8633638

Showing the first eight; more decompositions exist.
