Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33720, here are decompositions:

7 + 33713 = 33720
17 + 33703 = 33720
41 + 33679 = 33720
73 + 33647 = 33720
79 + 33641 = 33720
83 + 33637 = 33720
97 + 33623 = 33720
101 + 33619 = 33720

Showing the first eight; more decompositions exist.
