Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581918, here are decompositions:

61 + 33581857 = 33581918
127 + 33581791 = 33581918
151 + 33581767 = 33581918
157 + 33581761 = 33581918
211 + 33581707 = 33581918
241 + 33581677 = 33581918
397 + 33581521 = 33581918
619 + 33581299 = 33581918

Showing the first eight; more decompositions exist.
