Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597134, here are decompositions:

5 + 31597129 = 31597134
7 + 31597127 = 31597134
13 + 31597121 = 31597134
53 + 31597081 = 31597134
83 + 31597051 = 31597134
103 + 31597031 = 31597134
131 + 31597003 = 31597134
137 + 31596997 = 31597134

Showing the first eight; more decompositions exist.
