Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18706, here are decompositions:

  • 5 + 18701 = 18706
  • 89 + 18617 = 18706
  • 113 + 18593 = 18706
  • 167 + 18539 = 18706
  • 263 + 18443 = 18706
  • 293 + 18413 = 18706
  • 353 + 18353 = 18706
  • 419 + 18287 = 18706

Showing the first eight; more decompositions exist.
