Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40446, here are decompositions:

  • 13 + 40433 = 40446
  • 17 + 40429 = 40446
  • 19 + 40427 = 40446
  • 23 + 40423 = 40446
  • 59 + 40387 = 40446
  • 89 + 40357 = 40446
  • 103 + 40343 = 40446
  • 157 + 40289 = 40446

Showing the first eight; more decompositions exist.
