Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18446, here are decompositions:

  • 3 + 18443 = 18446
  • 7 + 18439 = 18446
  • 13 + 18433 = 18446
  • 19 + 18427 = 18446
  • 67 + 18379 = 18446
  • 79 + 18367 = 18446
  • 139 + 18307 = 18446
  • 157 + 18289 = 18446

Showing the first eight; more decompositions exist.
