Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597360, here are decompositions:

23 + 31597337 = 31597360
107 + 31597253 = 31597360
233 + 31597127 = 31597360
239 + 31597121 = 31597360
317 + 31597043 = 31597360
383 + 31596977 = 31597360
461 + 31596899 = 31597360
479 + 31596881 = 31597360

Showing the first eight; more decompositions exist.
