Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23942, here are decompositions:

  • 13 + 23929 = 23942
  • 31 + 23911 = 23942
  • 43 + 23899 = 23942
  • 73 + 23869 = 23942
  • 109 + 23833 = 23942
  • 181 + 23761 = 23942
  • 199 + 23743 = 23942
  • 223 + 23719 = 23942

Showing the first eight; more decompositions exist.
