Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33474728, here are decompositions:

31 + 33474697 = 33474728
61 + 33474667 = 33474728
97 + 33474631 = 33474728
127 + 33474601 = 33474728
151 + 33474577 = 33474728
241 + 33474487 = 33474728
337 + 33474391 = 33474728
379 + 33474349 = 33474728

Showing the first eight; more decompositions exist.
