Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23530, here are decompositions:

  • 71 + 23459 = 23530
  • 83 + 23447 = 23530
  • 113 + 23417 = 23530
  • 131 + 23399 = 23530
  • 173 + 23357 = 23530
  • 191 + 23339 = 23530
  • 197 + 23333 = 23530
  • 233 + 23297 = 23530

Showing the first eight; more decompositions exist.
