Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20066, here are decompositions:

  • 3 + 20063 = 20066
  • 19 + 20047 = 20066
  • 37 + 20029 = 20066
  • 43 + 20023 = 20066
  • 73 + 19993 = 20066
  • 103 + 19963 = 20066
  • 139 + 19927 = 20066
  • 199 + 19867 = 20066

Showing the first eight; more decompositions exist.
