Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513288, here are decompositions:

7 + 33513281 = 33513288
31 + 33513257 = 33513288
41 + 33513247 = 33513288
101 + 33513187 = 33513288
181 + 33513107 = 33513288
191 + 33513097 = 33513288
311 + 33512977 = 33513288
349 + 33512939 = 33513288

Showing the first eight; more decompositions exist.
