Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639446, here are decompositions:

  • 3 + 8639443 = 8639446
  • 5 + 8639441 = 8639446
  • 83 + 8639363 = 8639446
  • 173 + 8639273 = 8639446
  • 197 + 8639249 = 8639446
  • 227 + 8639219 = 8639446
  • 239 + 8639207 = 8639446
  • 269 + 8639177 = 8639446

Showing the first eight; more decompositions exist.
