Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669880, here are decompositions:

  • 19 + 8669861 = 8669880
  • 59 + 8669821 = 8669880
  • 103 + 8669777 = 8669880
  • 113 + 8669767 = 8669880
  • 179 + 8669701 = 8669880
  • 211 + 8669669 = 8669880
  • 223 + 8669657 = 8669880
  • 229 + 8669651 = 8669880

Showing the first eight; more decompositions exist.
