Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12342, here are decompositions:

  • 13 + 12329 = 12342
  • 19 + 12323 = 12342
  • 41 + 12301 = 12342
  • 53 + 12289 = 12342
  • 61 + 12281 = 12342
  • 73 + 12269 = 12342
  • 79 + 12263 = 12342
  • 89 + 12253 = 12342

Showing the first eight; more decompositions exist.
