Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597056, here are decompositions:

5 + 31597051 = 31597056
13 + 31597043 = 31597056
53 + 31597003 = 31597056
59 + 31596997 = 31597056
79 + 31596977 = 31597056
107 + 31596949 = 31597056
149 + 31596907 = 31597056
157 + 31596899 = 31597056

Showing the first eight; more decompositions exist.
