Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533662, here are decompositions:

3 + 31533659 = 31533662
31 + 31533631 = 31533662
151 + 31533511 = 31533662
163 + 31533499 = 31533662
211 + 31533451 = 31533662
283 + 31533379 = 31533662
571 + 31533091 = 31533662
661 + 31533001 = 31533662

Showing the first eight; more decompositions exist.
