Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533226, here are decompositions:

17 + 31533209 = 31533226
59 + 31533167 = 31533226
83 + 31533143 = 31533226
107 + 31533119 = 31533226
227 + 31532999 = 31533226
353 + 31532873 = 31533226
359 + 31532867 = 31533226
449 + 31532777 = 31533226

Showing the first eight; more decompositions exist.
