Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33533990, here are decompositions:

3 + 33533987 = 33533990
37 + 33533953 = 33533990
67 + 33533923 = 33533990
103 + 33533887 = 33533990
211 + 33533779 = 33533990
229 + 33533761 = 33533990
241 + 33533749 = 33533990
271 + 33533719 = 33533990

Showing the first eight; more decompositions exist.
