Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19600, here are decompositions:

  • 3 + 19597 = 19600
  • 17 + 19583 = 19600
  • 23 + 19577 = 19600
  • 29 + 19571 = 19600
  • 41 + 19559 = 19600
  • 47 + 19553 = 19600
  • 59 + 19541 = 19600
  • 131 + 19469 = 19600

Showing the first eight; more decompositions exist.
