Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86718, here are decompositions:

  • 7 + 86711 = 86718
  • 29 + 86689 = 86718
  • 41 + 86677 = 86718
  • 89 + 86629 = 86718
  • 131 + 86587 = 86718
  • 139 + 86579 = 86718
  • 157 + 86561 = 86718
  • 179 + 86539 = 86718

Showing the first eight; more decompositions exist.
