Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532936, here are decompositions:

13 + 31532923 = 31532936
37 + 31532899 = 31532936
73 + 31532863 = 31532936
103 + 31532833 = 31532936
199 + 31532737 = 31532936
277 + 31532659 = 31532936
283 + 31532653 = 31532936
349 + 31532587 = 31532936

Showing the first eight; more decompositions exist.
