Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597804, here are decompositions:

3 + 31597801 = 31597804
11 + 31597793 = 31597804
41 + 31597763 = 31597804
83 + 31597721 = 31597804
107 + 31597697 = 31597804
131 + 31597673 = 31597804
191 + 31597613 = 31597804
233 + 31597571 = 31597804

Showing the first eight; more decompositions exist.
