Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513168, here are decompositions:

5 + 33513163 = 33513168
41 + 33513127 = 33513168
61 + 33513107 = 33513168
67 + 33513101 = 33513168
71 + 33513097 = 33513168
181 + 33512987 = 33513168
191 + 33512977 = 33513168
229 + 33512939 = 33513168

Showing the first eight; more decompositions exist.
