Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533346, here are decompositions:

3 + 31533343 = 31533346
137 + 31533209 = 31533346
179 + 31533167 = 31533346
197 + 31533149 = 31533346
227 + 31533119 = 31533346
347 + 31532999 = 31533346
479 + 31532867 = 31533346
569 + 31532777 = 31533346

Showing the first eight; more decompositions exist.
