Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33474720, here are decompositions:

17 + 33474703 = 33474720
23 + 33474697 = 33474720
31 + 33474689 = 33474720
47 + 33474673 = 33474720
53 + 33474667 = 33474720
89 + 33474631 = 33474720
151 + 33474569 = 33474720
157 + 33474563 = 33474720

Showing the first eight; more decompositions exist.
