Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533934, here are decompositions:

11 + 31533923 = 31533934
23 + 31533911 = 31533934
101 + 31533833 = 31533934
227 + 31533707 = 31533934
293 + 31533641 = 31533934
347 + 31533587 = 31533934
353 + 31533581 = 31533934
401 + 31533533 = 31533934

Showing the first eight; more decompositions exist.
