Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544458, here are decompositions:

  • 41 + 31544417 = 31544458
  • 251 + 31544207 = 31544458
  • 269 + 31544189 = 31544458
  • 359 + 31544099 = 31544458
  • 401 + 31544057 = 31544458
  • 419 + 31544039 = 31544458
  • 461 + 31543997 = 31544458
  • 467 + 31543991 = 31544458

Showing the first eight; more decompositions exist.
