Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40628, here are decompositions:

  • 19 + 40609 = 40628
  • 31 + 40597 = 40628
  • 37 + 40591 = 40628
  • 97 + 40531 = 40628
  • 109 + 40519 = 40628
  • 157 + 40471 = 40628
  • 199 + 40429 = 40628
  • 241 + 40387 = 40628

Showing the first eight; more decompositions exist.
