Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597708, here are decompositions:

11 + 31597697 = 31597708
137 + 31597571 = 31597708
167 + 31597541 = 31597708
509 + 31597199 = 31597708
557 + 31597151 = 31597708
587 + 31597121 = 31597708
677 + 31597031 = 31597708
809 + 31596899 = 31597708

Showing the first eight; more decompositions exist.
