Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536876, here are decompositions:

5 + 31536871 = 31536876
13 + 31536863 = 31536876
29 + 31536847 = 31536876
47 + 31536829 = 31536876
53 + 31536823 = 31536876
83 + 31536793 = 31536876
103 + 31536773 = 31536876
157 + 31536719 = 31536876

Showing the first eight; more decompositions exist.
