Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84520, here are decompositions:

  • 11 + 84509 = 84520
  • 17 + 84503 = 84520
  • 53 + 84467 = 84520
  • 71 + 84449 = 84520
  • 83 + 84437 = 84520
  • 89 + 84431 = 84520
  • 113 + 84407 = 84520
  • 131 + 84389 = 84520

Showing the first eight; more decompositions exist.
