Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617922, here are decompositions:

  • 23 + 31617899 = 31617922
  • 59 + 31617863 = 31617922
  • 233 + 31617689 = 31617922
  • 263 + 31617659 = 31617922
  • 293 + 31617629 = 31617922
  • 359 + 31617563 = 31617922
  • 389 + 31617533 = 31617922
  • 419 + 31617503 = 31617922

Showing the first eight; more decompositions exist.
