Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33473778, here are decompositions:

11 + 33473767 = 33473778
29 + 33473749 = 33473778
31 + 33473747 = 33473778
97 + 33473681 = 33473778
101 + 33473677 = 33473778
179 + 33473599 = 33473778
227 + 33473551 = 33473778
229 + 33473549 = 33473778

Showing the first eight; more decompositions exist.
