Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505788, here are decompositions:

  • 7 + 505781 = 505788
  • 11 + 505777 = 505788
  • 29 + 505759 = 505788
  • 61 + 505727 = 505788
  • 79 + 505709 = 505788
  • 97 + 505691 = 505788
  • 131 + 505657 = 505788
  • 149 + 505639 = 505788

Showing the first eight; more decompositions exist.
