Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533310, here are decompositions:

41 + 31533269 = 31533310
101 + 31533209 = 31533310
167 + 31533143 = 31533310
191 + 31533119 = 31533310
311 + 31532999 = 31533310
443 + 31532867 = 31533310
617 + 31532693 = 31533310
821 + 31532489 = 31533310

Showing the first eight; more decompositions exist.
