Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597404, here are decompositions:

37 + 31597367 = 31597404
67 + 31597337 = 31597404
151 + 31597253 = 31597404
173 + 31597231 = 31597404
191 + 31597213 = 31597404
227 + 31597177 = 31597404
277 + 31597127 = 31597404
283 + 31597121 = 31597404

Showing the first eight; more decompositions exist.
