Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533382, here are decompositions:

3 + 31533379 = 31533382
11 + 31533371 = 31533382
113 + 31533269 = 31533382
173 + 31533209 = 31533382
191 + 31533191 = 31533382
233 + 31533149 = 31533382
239 + 31533143 = 31533382
263 + 31533119 = 31533382

Showing the first eight; more decompositions exist.
