Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12736, here are decompositions:

  • 23 + 12713 = 12736
  • 47 + 12689 = 12736
  • 83 + 12653 = 12736
  • 89 + 12647 = 12736
  • 167 + 12569 = 12736
  • 197 + 12539 = 12736
  • 233 + 12503 = 12736
  • 239 + 12497 = 12736

Showing the first eight; more decompositions exist.
