Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597710, here are decompositions:

13 + 31597697 = 31597710
17 + 31597693 = 31597710
37 + 31597673 = 31597710
59 + 31597651 = 31597710
71 + 31597639 = 31597710
97 + 31597613 = 31597710
107 + 31597603 = 31597710
139 + 31597571 = 31597710

Showing the first eight; more decompositions exist.
