Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8682440, here are decompositions:

  • 3 + 8682437 = 8682440
  • 7 + 8682433 = 8682440
  • 31 + 8682409 = 8682440
  • 37 + 8682403 = 8682440
  • 97 + 8682343 = 8682440
  • 163 + 8682277 = 8682440
  • 199 + 8682241 = 8682440
  • 211 + 8682229 = 8682440

Showing the first eight; more decompositions exist.
