Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669938, here are decompositions:

  • 41 + 8669897 = 8669938
  • 59 + 8669879 = 8669938
  • 107 + 8669831 = 8669938
  • 269 + 8669669 = 8669938
  • 281 + 8669657 = 8669938
  • 311 + 8669627 = 8669938
  • 317 + 8669621 = 8669938
  • 449 + 8669489 = 8669938

Showing the first eight; more decompositions exist.
