Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596158, here are decompositions:

7 + 31596151 = 31596158
31 + 31596127 = 31596158
37 + 31596121 = 31596158
109 + 31596049 = 31596158
151 + 31596007 = 31596158
229 + 31595929 = 31596158
277 + 31595881 = 31596158
439 + 31595719 = 31596158

Showing the first eight; more decompositions exist.
