Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597208, here are decompositions:

31 + 31597177 = 31597208
79 + 31597129 = 31597208
109 + 31597099 = 31597208
127 + 31597081 = 31597208
157 + 31597051 = 31597208
211 + 31596997 = 31597208
439 + 31596769 = 31597208
457 + 31596751 = 31597208

Showing the first eight; more decompositions exist.
