Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11586, here are decompositions:

  • 7 + 11579 = 11586
  • 37 + 11549 = 11586
  • 59 + 11527 = 11586
  • 67 + 11519 = 11586
  • 83 + 11503 = 11586
  • 89 + 11497 = 11586
  • 97 + 11489 = 11586
  • 103 + 11483 = 11586

Showing the first eight; more decompositions exist.
