Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598026, here are decompositions:

17 + 31598009 = 31598026
29 + 31597997 = 31598026
113 + 31597913 = 31598026
149 + 31597877 = 31598026
233 + 31597793 = 31598026
263 + 31597763 = 31598026
353 + 31597673 = 31598026
659 + 31597367 = 31598026

Showing the first eight; more decompositions exist.
