Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491960, here are decompositions:

31 + 33491929 = 33491960
43 + 33491917 = 33491960
127 + 33491833 = 33491960
157 + 33491803 = 33491960
181 + 33491779 = 33491960
193 + 33491767 = 33491960
199 + 33491761 = 33491960
241 + 33491719 = 33491960

Showing the first eight; more decompositions exist.
