Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513312, here are decompositions:

31 + 33513281 = 33513312
109 + 33513203 = 33513312
149 + 33513163 = 33513312
179 + 33513133 = 33513312
211 + 33513101 = 33513312
353 + 33512959 = 33513312
373 + 33512939 = 33513312
383 + 33512929 = 33513312

Showing the first eight; more decompositions exist.
