Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597746, here are decompositions:

7 + 31597739 = 31597746
17 + 31597729 = 31597746
29 + 31597717 = 31597746
53 + 31597693 = 31597746
73 + 31597673 = 31597746
107 + 31597639 = 31597746
197 + 31597549 = 31597746
239 + 31597507 = 31597746

Showing the first eight; more decompositions exist.
