Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458118, here are decompositions:

  • 5 + 31458113 = 31458118
  • 149 + 31457969 = 31458118
  • 257 + 31457861 = 31458118
  • 269 + 31457849 = 31458118
  • 347 + 31457771 = 31458118
  • 359 + 31457759 = 31458118
  • 389 + 31457729 = 31458118
  • 401 + 31457717 = 31458118

Showing the first eight; more decompositions exist.
