Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33591980, here are decompositions:

3 + 33591977 = 33591980
61 + 33591919 = 33591980
109 + 33591871 = 33591980
127 + 33591853 = 33591980
211 + 33591769 = 33591980
223 + 33591757 = 33591980
241 + 33591739 = 33591980
277 + 33591703 = 33591980

Showing the first eight; more decompositions exist.
