Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86740, here are decompositions:

  • 11 + 86729 = 86740
  • 29 + 86711 = 86740
  • 47 + 86693 = 86740
  • 113 + 86627 = 86740
  • 167 + 86573 = 86740
  • 179 + 86561 = 86740
  • 239 + 86501 = 86740
  • 263 + 86477 = 86740

Showing the first eight; more decompositions exist.
