Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533328, here are decompositions:

59 + 31533269 = 31533328
137 + 31533191 = 31533328
179 + 31533149 = 31533328
227 + 31533101 = 31533328
347 + 31532981 = 31533328
389 + 31532939 = 31533328
461 + 31532867 = 31533328
641 + 31532687 = 31533328

Showing the first eight; more decompositions exist.
