Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33638, here are decompositions:

19 + 33619 = 33638
37 + 33601 = 33638
61 + 33577 = 33638
109 + 33529 = 33638
151 + 33487 = 33638
181 + 33457 = 33638
211 + 33427 = 33638
229 + 33409 = 33638

Showing the first eight; more decompositions exist.
