Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597910, here are decompositions:

31 + 31597879 = 31597910
37 + 31597873 = 31597910
67 + 31597843 = 31597910
109 + 31597801 = 31597910
181 + 31597729 = 31597910
193 + 31597717 = 31597910
271 + 31597639 = 31597910
307 + 31597603 = 31597910

Showing the first eight; more decompositions exist.
