Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707970, here are decompositions:

31 + 8707939 = 8707970
67 + 8707903 = 8707970
97 + 8707873 = 8707970
109 + 8707861 = 8707970
127 + 8707843 = 8707970
223 + 8707747 = 8707970
283 + 8707687 = 8707970
367 + 8707603 = 8707970

Showing the first eight; more decompositions exist.
