Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597374, here are decompositions:

7 + 31597367 = 31597374
37 + 31597337 = 31597374
113 + 31597261 = 31597374
131 + 31597243 = 31597374
197 + 31597177 = 31597374
223 + 31597151 = 31597374
293 + 31597081 = 31597374
331 + 31597043 = 31597374

Showing the first eight; more decompositions exist.
