Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597356, here are decompositions:

19 + 31597337 = 31597356
73 + 31597283 = 31597356
103 + 31597253 = 31597356
113 + 31597243 = 31597356
157 + 31597199 = 31597356
179 + 31597177 = 31597356
227 + 31597129 = 31597356
229 + 31597127 = 31597356

Showing the first eight; more decompositions exist.
