Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533406, here are decompositions:

17 + 31533389 = 31533406
137 + 31533269 = 31533406
197 + 31533209 = 31533406
239 + 31533167 = 31533406
257 + 31533149 = 31533406
263 + 31533143 = 31533406
467 + 31532939 = 31533406
719 + 31532687 = 31533406

Showing the first eight; more decompositions exist.
