Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536984, here are decompositions:

  • 41 + 31536943 = 31536984
  • 47 + 31536937 = 31536984
  • 67 + 31536917 = 31536984
  • 113 + 31536871 = 31536984
  • 137 + 31536847 = 31536984
  • 163 + 31536821 = 31536984
  • 191 + 31536793 = 31536984
  • 211 + 31536773 = 31536984

Showing the first eight; more decompositions exist.
