Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596170, here are decompositions:

7 + 31596163 = 31596170
19 + 31596151 = 31596170
43 + 31596127 = 31596170
103 + 31596067 = 31596170
163 + 31596007 = 31596170
181 + 31595989 = 31596170
241 + 31595929 = 31596170
337 + 31595833 = 31596170

Showing the first eight; more decompositions exist.
