Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33474220, here are decompositions:

23 + 33474197 = 33474220
41 + 33474179 = 33474220
83 + 33474137 = 33474220
137 + 33474083 = 33474220
167 + 33474053 = 33474220
257 + 33473963 = 33474220
281 + 33473939 = 33474220
293 + 33473927 = 33474220

Showing the first eight; more decompositions exist.
