Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656858, here are decompositions:

  • 11 + 8656847 = 8656858
  • 29 + 8656829 = 8656858
  • 71 + 8656787 = 8656858
  • 131 + 8656727 = 8656858
  • 137 + 8656721 = 8656858
  • 167 + 8656691 = 8656858
  • 191 + 8656667 = 8656858
  • 269 + 8656589 = 8656858

Showing the first eight; more decompositions exist.
