Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492108, here are decompositions:

  • 17 + 31492091 = 31492108
  • 29 + 31492079 = 31492108
  • 41 + 31492067 = 31492108
  • 47 + 31492061 = 31492108
  • 149 + 31491959 = 31492108
  • 191 + 31491917 = 31492108
  • 227 + 31491881 = 31492108
  • 317 + 31491791 = 31492108

Showing the first eight; more decompositions exist.
