Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33890, here are decompositions:

19 + 33871 = 33890
61 + 33829 = 33890
79 + 33811 = 33890
139 + 33751 = 33890
151 + 33739 = 33890
211 + 33679 = 33890
271 + 33619 = 33890
277 + 33613 = 33890

Showing the first eight; more decompositions exist.
