Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21592, here are decompositions:

  • 3 + 21589 = 21592
  • 5 + 21587 = 21592
  • 23 + 21569 = 21592
  • 29 + 21563 = 21592
  • 71 + 21521 = 21592
  • 89 + 21503 = 21592
  • 101 + 21491 = 21592
  • 173 + 21419 = 21592

Showing the first eight; more decompositions exist.
