Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596164, here are decompositions:

13 + 31596151 = 31596164
37 + 31596127 = 31596164
43 + 31596121 = 31596164
97 + 31596067 = 31596164
157 + 31596007 = 31596164
181 + 31595983 = 31596164
283 + 31595881 = 31596164
331 + 31595833 = 31596164

Showing the first eight; more decompositions exist.
