Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533316, here are decompositions:

47 + 31533269 = 31533316
107 + 31533209 = 31533316
149 + 31533167 = 31533316
167 + 31533149 = 31533316
173 + 31533143 = 31533316
197 + 31533119 = 31533316
317 + 31532999 = 31533316
443 + 31532873 = 31533316

Showing the first eight; more decompositions exist.
