Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11500, here are decompositions:

  • 3 + 11497 = 11500
  • 11 + 11489 = 11500
  • 17 + 11483 = 11500
  • 29 + 11471 = 11500
  • 53 + 11447 = 11500
  • 89 + 11411 = 11500
  • 101 + 11399 = 11500
  • 107 + 11393 = 11500

Showing the first eight; more decompositions exist.
