Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617392, here are decompositions:

  • 13 + 31617379 = 31617392
  • 19 + 31617373 = 31617392
  • 31 + 31617361 = 31617392
  • 109 + 31617283 = 31617392
  • 139 + 31617253 = 31617392
  • 193 + 31617199 = 31617392
  • 211 + 31617181 = 31617392
  • 379 + 31617013 = 31617392

Showing the first eight; more decompositions exist.
