Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596018, here are decompositions:

11 + 31596007 = 31596018
29 + 31595989 = 31596018
89 + 31595929 = 31596018
137 + 31595881 = 31596018
149 + 31595869 = 31596018
151 + 31595867 = 31596018
211 + 31595807 = 31596018
241 + 31595777 = 31596018

Showing the first eight; more decompositions exist.
