Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526970, here are decompositions:

  • 17 + 31526953 = 31526970
  • 29 + 31526941 = 31526970
  • 31 + 31526939 = 31526970
  • 43 + 31526927 = 31526970
  • 67 + 31526903 = 31526970
  • 71 + 31526899 = 31526970
  • 89 + 31526881 = 31526970
  • 107 + 31526863 = 31526970

Showing the first eight; more decompositions exist.
