Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669868, here are decompositions:

  • 7 + 8669861 = 8669868
  • 37 + 8669831 = 8669868
  • 47 + 8669821 = 8669868
  • 101 + 8669767 = 8669868
  • 167 + 8669701 = 8669868
  • 197 + 8669671 = 8669868
  • 199 + 8669669 = 8669868
  • 211 + 8669657 = 8669868

Showing the first eight; more decompositions exist.
