Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705686, here are decompositions:

  • 5 + 8705681 = 8705686
  • 29 + 8705657 = 8705686
  • 47 + 8705639 = 8705686
  • 113 + 8705573 = 8705686
  • 137 + 8705549 = 8705686
  • 167 + 8705519 = 8705686
  • 179 + 8705507 = 8705686
  • 233 + 8705453 = 8705686

Showing the first eight; more decompositions exist.
