Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597962, here are decompositions:

29 + 31597933 = 31597962
83 + 31597879 = 31597962
89 + 31597873 = 31597962
139 + 31597823 = 31597962
199 + 31597763 = 31597962
223 + 31597739 = 31597962
233 + 31597729 = 31597962
241 + 31597721 = 31597962

Showing the first eight; more decompositions exist.
