Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533354, here are decompositions:

11 + 31533343 = 31533354
163 + 31533191 = 31533354
211 + 31533143 = 31533354
227 + 31533127 = 31533354
257 + 31533097 = 31533354
263 + 31533091 = 31533354
353 + 31533001 = 31533354
373 + 31532981 = 31533354

Showing the first eight; more decompositions exist.
