Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597384, here are decompositions:

17 + 31597367 = 31597384
47 + 31597337 = 31597384
101 + 31597283 = 31597384
131 + 31597253 = 31597384
233 + 31597151 = 31597384
257 + 31597127 = 31597384
263 + 31597121 = 31597384
353 + 31597031 = 31597384

Showing the first eight; more decompositions exist.
