Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596180, here are decompositions:

  • 17 + 31596163 = 31596180
  • 29 + 31596151 = 31596180
  • 37 + 31596143 = 31596180
  • 53 + 31596127 = 31596180
  • 59 + 31596121 = 31596180
  • 61 + 31596119 = 31596180
  • 113 + 31596067 = 31596180
  • 131 + 31596049 = 31596180

Showing the first eight; more decompositions exist.
