Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19500, here are decompositions:

  • 11 + 19489 = 19500
  • 17 + 19483 = 19500
  • 23 + 19477 = 19500
  • 29 + 19471 = 19500
  • 31 + 19469 = 19500
  • 37 + 19463 = 19500
  • 43 + 19457 = 19500
  • 53 + 19447 = 19500

Showing the first eight; more decompositions exist.
