Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596210, here are decompositions:

17 + 31596193 = 31596210
47 + 31596163 = 31596210
59 + 31596151 = 31596210
67 + 31596143 = 31596210
83 + 31596127 = 31596210
89 + 31596121 = 31596210
181 + 31596029 = 31596210
227 + 31595983 = 31596210

Showing the first eight; more decompositions exist.
