Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669906, here are decompositions:

  • 13 + 8669893 = 8669906
  • 139 + 8669767 = 8669906
  • 277 + 8669629 = 8669906
  • 283 + 8669623 = 8669906
  • 313 + 8669593 = 8669906
  • 379 + 8669527 = 8669906
  • 463 + 8669443 = 8669906
  • 577 + 8669329 = 8669906

Showing the first eight; more decompositions exist.
