Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33728, here are decompositions:

7 + 33721 = 33728
109 + 33619 = 33728
127 + 33601 = 33728
139 + 33589 = 33728
151 + 33577 = 33728
181 + 33547 = 33728
199 + 33529 = 33728
241 + 33487 = 33728

Showing the first eight; more decompositions exist.
