Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536852, here are decompositions:

5 + 31536847 = 31536852
23 + 31536829 = 31536852
29 + 31536823 = 31536852
31 + 31536821 = 31536852
59 + 31536793 = 31536852
79 + 31536773 = 31536852
223 + 31536629 = 31536852
239 + 31536613 = 31536852

Showing the first eight; more decompositions exist.
