Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585306, here are decompositions:

  • 17 + 31585289 = 31585306
  • 89 + 31585217 = 31585306
  • 107 + 31585199 = 31585306
  • 113 + 31585193 = 31585306
  • 167 + 31585139 = 31585306
  • 227 + 31585079 = 31585306
  • 239 + 31585067 = 31585306
  • 353 + 31584953 = 31585306

Showing the first eight; more decompositions exist.
