Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686636, here are decompositions:

  • 47 + 8686589 = 8686636
  • 107 + 8686529 = 8686636
  • 137 + 8686499 = 8686636
  • 149 + 8686487 = 8686636
  • 173 + 8686463 = 8686636
  • 227 + 8686409 = 8686636
  • 239 + 8686397 = 8686636
  • 263 + 8686373 = 8686636

Showing the first eight; more decompositions exist.
