Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597924, here are decompositions:

11 + 31597913 = 31597924
47 + 31597877 = 31597924
101 + 31597823 = 31597924
131 + 31597793 = 31597924
227 + 31597697 = 31597924
251 + 31597673 = 31597924
311 + 31597613 = 31597924
353 + 31597571 = 31597924

Showing the first eight; more decompositions exist.
