Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597674, here are decompositions:

23 + 31597651 = 31597674
61 + 31597613 = 31597674
71 + 31597603 = 31597674
103 + 31597571 = 31597674
167 + 31597507 = 31597674
181 + 31597493 = 31597674
191 + 31597483 = 31597674
257 + 31597417 = 31597674

Showing the first eight; more decompositions exist.
