Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596970, here are decompositions:

47 + 31596923 = 31596970
71 + 31596899 = 31596970
89 + 31596881 = 31596970
113 + 31596857 = 31596970
131 + 31596839 = 31596970
149 + 31596821 = 31596970
173 + 31596797 = 31596970
227 + 31596743 = 31596970

Showing the first eight; more decompositions exist.
