Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513172, here are decompositions:

5 + 33513167 = 33513172
71 + 33513101 = 33513172
149 + 33513023 = 33513172
233 + 33512939 = 33513172
389 + 33512783 = 33513172
419 + 33512753 = 33513172
449 + 33512723 = 33513172
491 + 33512681 = 33513172

Showing the first eight; more decompositions exist.
