Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597824, here are decompositions:

23 + 31597801 = 31597824
31 + 31597793 = 31597824
47 + 31597777 = 31597824
61 + 31597763 = 31597824
103 + 31597721 = 31597824
107 + 31597717 = 31597824
127 + 31597697 = 31597824
131 + 31597693 = 31597824

Showing the first eight; more decompositions exist.
