Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597182, here are decompositions:

5 + 31597177 = 31597182
31 + 31597151 = 31597182
53 + 31597129 = 31597182
61 + 31597121 = 31597182
83 + 31597099 = 31597182
101 + 31597081 = 31597182
131 + 31597051 = 31597182
139 + 31597043 = 31597182

Showing the first eight; more decompositions exist.
