Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491920, here are decompositions:

3 + 33491917 = 33491920
71 + 33491849 = 33491920
83 + 33491837 = 33491920
89 + 33491831 = 33491920
173 + 33491747 = 33491920
179 + 33491741 = 33491920
191 + 33491729 = 33491920
227 + 33491693 = 33491920

Showing the first eight; more decompositions exist.
