Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533670, here are decompositions:

11 + 31533659 = 31533670
29 + 31533641 = 31533670
59 + 31533611 = 31533670
71 + 31533599 = 31533670
83 + 31533587 = 31533670
89 + 31533581 = 31533670
107 + 31533563 = 31533670
137 + 31533533 = 31533670

Showing the first eight; more decompositions exist.
