Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507108, here are decompositions:

  • 71 + 31507037 = 31507108
  • 131 + 31506977 = 31507108
  • 179 + 31506929 = 31507108
  • 197 + 31506911 = 31507108
  • 317 + 31506791 = 31507108
  • 359 + 31506749 = 31507108
  • 389 + 31506719 = 31507108
  • 419 + 31506689 = 31507108

Showing the first eight; more decompositions exist.
