Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570976, here are decompositions:

37 + 31570939 = 31570976
67 + 31570909 = 31570976
103 + 31570873 = 31570976
109 + 31570867 = 31570976
373 + 31570603 = 31570976
457 + 31570519 = 31570976
673 + 31570303 = 31570976
727 + 31570249 = 31570976

Showing the first eight; more decompositions exist.
