Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533166, here are decompositions:

17 + 31533149 = 31533166
23 + 31533143 = 31533166
47 + 31533119 = 31533166
167 + 31532999 = 31533166
227 + 31532939 = 31533166
293 + 31532873 = 31533166
389 + 31532777 = 31533166
479 + 31532687 = 31533166

Showing the first eight; more decompositions exist.
