Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544566, here are decompositions:

  • 5 + 31544561 = 31544566
  • 23 + 31544543 = 31544566
  • 149 + 31544417 = 31544566
  • 173 + 31544393 = 31544566
  • 269 + 31544297 = 31544566
  • 353 + 31544213 = 31544566
  • 359 + 31544207 = 31544566
  • 467 + 31544099 = 31544566

Showing the first eight; more decompositions exist.
