Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86800, here are decompositions:

  • 17 + 86783 = 86800
  • 29 + 86771 = 86800
  • 47 + 86753 = 86800
  • 71 + 86729 = 86800
  • 89 + 86711 = 86800
  • 107 + 86693 = 86800
  • 173 + 86627 = 86800
  • 227 + 86573 = 86800

Showing the first eight; more decompositions exist.
