Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718874, here are decompositions:

  • 5 + 8718869 = 8718874
  • 23 + 8718851 = 8718874
  • 41 + 8718833 = 8718874
  • 71 + 8718803 = 8718874
  • 137 + 8718737 = 8718874
  • 293 + 8718581 = 8718874
  • 383 + 8718491 = 8718874
  • 443 + 8718431 = 8718874

Showing the first eight; more decompositions exist.
