Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597858, here are decompositions:

137 + 31597721 = 31597858
317 + 31597541 = 31597858
491 + 31597367 = 31597858
521 + 31597337 = 31597858
659 + 31597199 = 31597858
827 + 31597031 = 31597858
881 + 31596977 = 31597858
977 + 31596881 = 31597858

Showing the first eight; more decompositions exist.
