Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597568, here are decompositions:

19 + 31597549 = 31597568
61 + 31597507 = 31597568
97 + 31597471 = 31597568
151 + 31597417 = 31597568
157 + 31597411 = 31597568
307 + 31597261 = 31597568
337 + 31597231 = 31597568
439 + 31597129 = 31597568

Showing the first eight; more decompositions exist.
