Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597162, here are decompositions:

11 + 31597151 = 31597162
41 + 31597121 = 31597162
131 + 31597031 = 31597162
239 + 31596923 = 31597162
263 + 31596899 = 31597162
281 + 31596881 = 31597162
419 + 31596743 = 31597162
449 + 31596713 = 31597162

Showing the first eight; more decompositions exist.
