Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596166, here are decompositions:

3 + 31596163 = 31596166
23 + 31596143 = 31596166
47 + 31596119 = 31596166
137 + 31596029 = 31596166
197 + 31595969 = 31596166
293 + 31595873 = 31596166
359 + 31595807 = 31596166
383 + 31595783 = 31596166

Showing the first eight; more decompositions exist.
