Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491918, here are decompositions:

139 + 33491779 = 33491918
151 + 33491767 = 33491918
157 + 33491761 = 33491918
199 + 33491719 = 33491918
277 + 33491641 = 33491918
349 + 33491569 = 33491918
457 + 33491461 = 33491918
547 + 33491371 = 33491918

Showing the first eight; more decompositions exist.
