Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513940, here are decompositions:

29 + 33513911 = 33513940
59 + 33513881 = 33513940
101 + 33513839 = 33513940
179 + 33513761 = 33513940
227 + 33513713 = 33513940
233 + 33513707 = 33513940
281 + 33513659 = 33513940
311 + 33513629 = 33513940

Showing the first eight; more decompositions exist.
