Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945686, here are decompositions:

  • 13 + 945673 = 945686
  • 97 + 945589 = 945686
  • 109 + 945577 = 945686
  • 139 + 945547 = 945686
  • 223 + 945463 = 945686
  • 229 + 945457 = 945686
  • 277 + 945409 = 945686
  • 337 + 945349 = 945686

Showing the first eight; more decompositions exist.
