Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648686, here are decompositions:

  • 149 + 8648537 = 8648686
  • 173 + 8648513 = 8648686
  • 227 + 8648459 = 8648686
  • 239 + 8648447 = 8648686
  • 317 + 8648369 = 8648686
  • 353 + 8648333 = 8648686
  • 419 + 8648267 = 8648686
  • 587 + 8648099 = 8648686

Showing the first eight; more decompositions exist.
