Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597882, here are decompositions:

3 + 31597879 = 31597882
5 + 31597877 = 31597882
59 + 31597823 = 31597882
89 + 31597793 = 31597882
269 + 31597613 = 31597882
311 + 31597571 = 31597882
389 + 31597493 = 31597882
599 + 31597283 = 31597882

Showing the first eight; more decompositions exist.
