Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591962, here are decompositions:

5 + 31591957 = 31591962
53 + 31591909 = 31591962
89 + 31591873 = 31591962
179 + 31591783 = 31591962
211 + 31591751 = 31591962
223 + 31591739 = 31591962
229 + 31591733 = 31591962
239 + 31591723 = 31591962

Showing the first eight; more decompositions exist.
