Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533822, here are decompositions:

31 + 31533791 = 31533822
53 + 31533769 = 31533822
59 + 31533763 = 31533822
101 + 31533721 = 31533822
163 + 31533659 = 31533822
181 + 31533641 = 31533822
191 + 31533631 = 31533822
211 + 31533611 = 31533822

Showing the first eight; more decompositions exist.
