Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597794, here are decompositions:

17 + 31597777 = 31597794
31 + 31597763 = 31597794
73 + 31597721 = 31597794
97 + 31597697 = 31597794
101 + 31597693 = 31597794
181 + 31597613 = 31597794
191 + 31597603 = 31597794
223 + 31597571 = 31597794

Showing the first eight; more decompositions exist.
