Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673786, here are decompositions:

  • 5 + 8673781 = 8673786
  • 59 + 8673727 = 8673786
  • 83 + 8673703 = 8673786
  • 103 + 8673683 = 8673786
  • 109 + 8673677 = 8673786
  • 193 + 8673593 = 8673786
  • 239 + 8673547 = 8673786
  • 269 + 8673517 = 8673786

Showing the first eight; more decompositions exist.
