Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490288, here are decompositions:

17 + 33490271 = 33490288
47 + 33490241 = 33490288
107 + 33490181 = 33490288
179 + 33490109 = 33490288
191 + 33490097 = 33490288
197 + 33490091 = 33490288
257 + 33490031 = 33490288
281 + 33490007 = 33490288

Showing the first eight; more decompositions exist.
