Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68666, here are decompositions:

  • 7 + 68659 = 68666
  • 127 + 68539 = 68666
  • 193 + 68473 = 68666
  • 223 + 68443 = 68666
  • 229 + 68437 = 68666
  • 277 + 68389 = 68666
  • 337 + 68329 = 68666
  • 439 + 68227 = 68666

Showing the first eight; more decompositions exist.
