Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596230, here are decompositions:

37 + 31596193 = 31596230
67 + 31596163 = 31596230
79 + 31596151 = 31596230
103 + 31596127 = 31596230
109 + 31596121 = 31596230
163 + 31596067 = 31596230
181 + 31596049 = 31596230
223 + 31596007 = 31596230

Showing the first eight; more decompositions exist.
