Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532910, here are decompositions:

11 + 31532899 = 31532910
29 + 31532881 = 31532910
37 + 31532873 = 31532910
43 + 31532867 = 31532910
47 + 31532863 = 31532910
173 + 31532737 = 31532910
223 + 31532687 = 31532910
251 + 31532659 = 31532910

Showing the first eight; more decompositions exist.
