Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39970, here are decompositions:

  • 17 + 39953 = 39970
  • 41 + 39929 = 39970
  • 83 + 39887 = 39970
  • 101 + 39869 = 39970
  • 107 + 39863 = 39970
  • 113 + 39857 = 39970
  • 131 + 39839 = 39970
  • 149 + 39821 = 39970

Showing the first eight; more decompositions exist.
