Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596174, here are decompositions:

11 + 31596163 = 31596174
23 + 31596151 = 31596174
31 + 31596143 = 31596174
47 + 31596127 = 31596174
53 + 31596121 = 31596174
107 + 31596067 = 31596174
167 + 31596007 = 31596174
191 + 31595983 = 31596174

Showing the first eight; more decompositions exist.
