Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532960, here are decompositions:

37 + 31532923 = 31532960
61 + 31532899 = 31532960
79 + 31532881 = 31532960
97 + 31532863 = 31532960
127 + 31532833 = 31532960
211 + 31532749 = 31532960
223 + 31532737 = 31532960
307 + 31532653 = 31532960

Showing the first eight; more decompositions exist.
