Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533334, here are decompositions:

167 + 31533167 = 31533334
191 + 31533143 = 31533334
233 + 31533101 = 31533334
353 + 31532981 = 31533334
461 + 31532873 = 31533334
467 + 31532867 = 31533334
557 + 31532777 = 31533334
641 + 31532693 = 31533334

Showing the first eight; more decompositions exist.
