Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724736, here are decompositions:

  • 17 + 8724719 = 8724736
  • 23 + 8724713 = 8724736
  • 239 + 8724497 = 8724736
  • 257 + 8724479 = 8724736
  • 269 + 8724467 = 8724736
  • 359 + 8724377 = 8724736
  • 389 + 8724347 = 8724736
  • 443 + 8724293 = 8724736

Showing the first eight; more decompositions exist.
