Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469684, here are decompositions:

  • 13 + 31469671 = 31469684
  • 31 + 31469653 = 31469684
  • 61 + 31469623 = 31469684
  • 97 + 31469587 = 31469684
  • 157 + 31469527 = 31469684
  • 241 + 31469443 = 31469684
  • 277 + 31469407 = 31469684
  • 331 + 31469353 = 31469684

Showing the first eight; more decompositions exist.
