Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597734, here are decompositions:

5 + 31597729 = 31597734
13 + 31597721 = 31597734
17 + 31597717 = 31597734
37 + 31597697 = 31597734
41 + 31597693 = 31597734
61 + 31597673 = 31597734
83 + 31597651 = 31597734
131 + 31597603 = 31597734

Showing the first eight; more decompositions exist.
