Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469550, here are decompositions:

  • 19 + 31469531 = 31469550
  • 23 + 31469527 = 31469550
  • 31 + 31469519 = 31469550
  • 37 + 31469513 = 31469550
  • 83 + 31469467 = 31469550
  • 103 + 31469447 = 31469550
  • 107 + 31469443 = 31469550
  • 109 + 31469441 = 31469550

Showing the first eight; more decompositions exist.
