Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489938, here are decompositions:

7 + 33489931 = 33489938
37 + 33489901 = 33489938
61 + 33489877 = 33489938
67 + 33489871 = 33489938
109 + 33489829 = 33489938
199 + 33489739 = 33489938
211 + 33489727 = 33489938
379 + 33489559 = 33489938

Showing the first eight; more decompositions exist.
