Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86824, here are decompositions:

  • 11 + 86813 = 86824
  • 41 + 86783 = 86824
  • 53 + 86771 = 86824
  • 71 + 86753 = 86824
  • 113 + 86711 = 86824
  • 131 + 86693 = 86824
  • 197 + 86627 = 86824
  • 251 + 86573 = 86824

Showing the first eight; more decompositions exist.
