Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512178, here are decompositions:

41 + 33512137 = 33512178
67 + 33512111 = 33512178
79 + 33512099 = 33512178
109 + 33512069 = 33512178
199 + 33511979 = 33512178
211 + 33511967 = 33512178
229 + 33511949 = 33512178
239 + 33511939 = 33512178

Showing the first eight; more decompositions exist.
