Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33920, here are decompositions:

31 + 33889 = 33920
109 + 33811 = 33920
151 + 33769 = 33920
163 + 33757 = 33920
181 + 33739 = 33920
199 + 33721 = 33920
241 + 33679 = 33920
283 + 33637 = 33920

Showing the first eight; more decompositions exist.
