Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33501920, here are decompositions:

13 + 33501907 = 33501920
31 + 33501889 = 33501920
79 + 33501841 = 33501920
211 + 33501709 = 33501920
223 + 33501697 = 33501920
229 + 33501691 = 33501920
271 + 33501649 = 33501920
349 + 33501571 = 33501920

Showing the first eight; more decompositions exist.
