Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536882, here are decompositions:

11 + 31536871 = 31536882
19 + 31536863 = 31536882
53 + 31536829 = 31536882
59 + 31536823 = 31536882
61 + 31536821 = 31536882
89 + 31536793 = 31536882
109 + 31536773 = 31536882
149 + 31536733 = 31536882

Showing the first eight; more decompositions exist.
