Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509742, here are decompositions:

  • 5 + 509737 = 509742
  • 11 + 509731 = 509742
  • 19 + 509723 = 509742
  • 43 + 509699 = 509742
  • 53 + 509689 = 509742
  • 61 + 509681 = 509742
  • 83 + 509659 = 509742
  • 89 + 509653 = 509742

Showing the first eight; more decompositions exist.
