Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11562, here are decompositions:

  • 11 + 11551 = 11562
  • 13 + 11549 = 11562
  • 43 + 11519 = 11562
  • 59 + 11503 = 11562
  • 71 + 11491 = 11562
  • 73 + 11489 = 11562
  • 79 + 11483 = 11562
  • 139 + 11423 = 11562

Showing the first eight; more decompositions exist.
