Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533622, here are decompositions:

11 + 31533611 = 31533622
23 + 31533599 = 31533622
41 + 31533581 = 31533622
59 + 31533563 = 31533622
89 + 31533533 = 31533622
173 + 31533449 = 31533622
191 + 31533431 = 31533622
233 + 31533389 = 31533622

Showing the first eight; more decompositions exist.
