Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512784, here are decompositions:

  • 5 + 512779 = 512784
  • 17 + 512767 = 512784
  • 23 + 512761 = 512784
  • 37 + 512747 = 512784
  • 43 + 512741 = 512784
  • 67 + 512717 = 512784
  • 71 + 512713 = 512784
  • 73 + 512711 = 512784

Showing the first eight; more decompositions exist.
