Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728822, here are decompositions:

  • 101 + 8728721 = 8728822
  • 131 + 8728691 = 8728822
  • 173 + 8728649 = 8728822
  • 251 + 8728571 = 8728822
  • 449 + 8728373 = 8728822
  • 491 + 8728331 = 8728822
  • 653 + 8728169 = 8728822
  • 743 + 8728079 = 8728822

Showing the first eight; more decompositions exist.
