Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597464, here are decompositions:

11 + 31597453 = 31597464
47 + 31597417 = 31597464
53 + 31597411 = 31597464
97 + 31597367 = 31597464
127 + 31597337 = 31597464
181 + 31597283 = 31597464
211 + 31597253 = 31597464
233 + 31597231 = 31597464

Showing the first eight; more decompositions exist.
