Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533762, here are decompositions:

41 + 31533721 = 31533762
101 + 31533661 = 31533762
103 + 31533659 = 31533762
131 + 31533631 = 31533762
149 + 31533613 = 31533762
151 + 31533611 = 31533762
163 + 31533599 = 31533762
181 + 31533581 = 31533762

Showing the first eight; more decompositions exist.
