Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597132, here are decompositions:

3 + 31597129 = 31597132
5 + 31597127 = 31597132
11 + 31597121 = 31597132
89 + 31597043 = 31597132
101 + 31597031 = 31597132
233 + 31596899 = 31597132
251 + 31596881 = 31597132
293 + 31596839 = 31597132

Showing the first eight; more decompositions exist.
