Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597036, here are decompositions:

5 + 31597031 = 31597036
59 + 31596977 = 31597036
113 + 31596923 = 31597036
137 + 31596899 = 31597036
179 + 31596857 = 31597036
197 + 31596839 = 31597036
239 + 31596797 = 31597036
293 + 31596743 = 31597036

Showing the first eight; more decompositions exist.
