Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706840, here are decompositions:

  • 7 + 8706833 = 8706840
  • 11 + 8706829 = 8706840
  • 17 + 8706823 = 8706840
  • 47 + 8706793 = 8706840
  • 89 + 8706751 = 8706840
  • 97 + 8706743 = 8706840
  • 113 + 8706727 = 8706840
  • 173 + 8706667 = 8706840

Showing the first eight; more decompositions exist.
