Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537970, here are decompositions:

31 + 31537939 = 31537970
67 + 31537903 = 31537970
109 + 31537861 = 31537970
127 + 31537843 = 31537970
223 + 31537747 = 31537970
229 + 31537741 = 31537970
283 + 31537687 = 31537970
367 + 31537603 = 31537970

Showing the first eight; more decompositions exist.
