Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31416, here are decompositions:

  • 19 + 31397 = 31416
  • 23 + 31393 = 31416
  • 29 + 31387 = 31416
  • 37 + 31379 = 31416
  • 59 + 31357 = 31416
  • 79 + 31337 = 31416
  • 83 + 31333 = 31416
  • 89 + 31327 = 31416

Showing the first eight; more decompositions exist.
