Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8633388, here are decompositions:

7 + 8633381 = 8633388
11 + 8633377 = 8633388
17 + 8633371 = 8633388
41 + 8633347 = 8633388
61 + 8633327 = 8633388
107 + 8633281 = 8633388
109 + 8633279 = 8633388
151 + 8633237 = 8633388

Showing the first eight; more decompositions exist.
