Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33502820, here are decompositions:

3 + 33502817 = 33502820
7 + 33502813 = 33502820
37 + 33502783 = 33502820
103 + 33502717 = 33502820
163 + 33502657 = 33502820
181 + 33502639 = 33502820
229 + 33502591 = 33502820
277 + 33502543 = 33502820

Showing the first eight; more decompositions exist.
