Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513138, here are decompositions:

5 + 33513133 = 33513138
11 + 33513127 = 33513138
31 + 33513107 = 33513138
37 + 33513101 = 33513138
41 + 33513097 = 33513138
151 + 33512987 = 33513138
179 + 33512959 = 33513138
199 + 33512939 = 33513138

Showing the first eight; more decompositions exist.
