Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605874, here are decompositions:

  • 71 + 31605803 = 31605874
  • 101 + 31605773 = 31605874
  • 173 + 31605701 = 31605874
  • 281 + 31605593 = 31605874
  • 317 + 31605557 = 31605874
  • 383 + 31605491 = 31605874
  • 431 + 31605443 = 31605874
  • 467 + 31605407 = 31605874

Showing the first eight; more decompositions exist.
