Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33664, here are decompositions:

17 + 33647 = 33664
23 + 33641 = 33664
41 + 33623 = 33664
47 + 33617 = 33664
83 + 33581 = 33664
101 + 33563 = 33664
131 + 33533 = 33664
251 + 33413 = 33664

Showing the first eight; more decompositions exist.
