Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533376, here are decompositions:

5 + 31533371 = 31533376
107 + 31533269 = 31533376
167 + 31533209 = 31533376
227 + 31533149 = 31533376
233 + 31533143 = 31533376
257 + 31533119 = 31533376
503 + 31532873 = 31533376
509 + 31532867 = 31533376

Showing the first eight; more decompositions exist.
