Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33502728, here are decompositions:

11 + 33502717 = 33502728
19 + 33502709 = 33502728
37 + 33502691 = 33502728
71 + 33502657 = 33502728
89 + 33502639 = 33502728
137 + 33502591 = 33502728
151 + 33502577 = 33502728
167 + 33502561 = 33502728

Showing the first eight; more decompositions exist.
