Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491982, here are decompositions:

5 + 33491977 = 33491982
23 + 33491959 = 33491982
53 + 33491929 = 33491982
149 + 33491833 = 33491982
151 + 33491831 = 33491982
179 + 33491803 = 33491982
241 + 33491741 = 33491982
263 + 33491719 = 33491982

Showing the first eight; more decompositions exist.
