Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669784, here are decompositions:

  • 7 + 8669777 = 8669784
  • 17 + 8669767 = 8669784
  • 83 + 8669701 = 8669784
  • 113 + 8669671 = 8669784
  • 127 + 8669657 = 8669784
  • 157 + 8669627 = 8669784
  • 163 + 8669621 = 8669784
  • 173 + 8669611 = 8669784

Showing the first eight; more decompositions exist.
