Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513272, here are decompositions:

109 + 33513163 = 33513272
139 + 33513133 = 33513272
313 + 33512959 = 33513272
433 + 33512839 = 33513272
601 + 33512671 = 33513272
619 + 33512653 = 33513272
631 + 33512641 = 33513272
643 + 33512629 = 33513272

Showing the first eight; more decompositions exist.
