Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597806, here are decompositions:

5 + 31597801 = 31597806
13 + 31597793 = 31597806
29 + 31597777 = 31597806
43 + 31597763 = 31597806
67 + 31597739 = 31597806
89 + 31597717 = 31597806
109 + 31597697 = 31597806
113 + 31597693 = 31597806

Showing the first eight; more decompositions exist.
