Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533682, here are decompositions:

23 + 31533659 = 31533682
41 + 31533641 = 31533682
71 + 31533611 = 31533682
83 + 31533599 = 31533682
101 + 31533581 = 31533682
149 + 31533533 = 31533682
233 + 31533449 = 31533682
251 + 31533431 = 31533682

Showing the first eight; more decompositions exist.
