Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533882, here are decompositions:

11 + 31533871 = 31533882
43 + 31533839 = 31533882
53 + 31533829 = 31533882
59 + 31533823 = 31533882
109 + 31533773 = 31533882
113 + 31533769 = 31533882
223 + 31533659 = 31533882
241 + 31533641 = 31533882

Showing the first eight; more decompositions exist.
