Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597704, here are decompositions:

7 + 31597697 = 31597704
11 + 31597693 = 31597704
31 + 31597673 = 31597704
53 + 31597651 = 31597704
101 + 31597603 = 31597704
163 + 31597541 = 31597704
197 + 31597507 = 31597704
211 + 31597493 = 31597704

Showing the first eight; more decompositions exist.
