Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513280, here are decompositions:

23 + 33513257 = 33513280
83 + 33513197 = 33513280
113 + 33513167 = 33513280
173 + 33513107 = 33513280
179 + 33513101 = 33513280
257 + 33513023 = 33513280
293 + 33512987 = 33513280
443 + 33512837 = 33513280

Showing the first eight; more decompositions exist.
