Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66006, here are decompositions:

  • 13 + 65993 = 66006
  • 23 + 65983 = 66006
  • 43 + 65963 = 66006
  • 79 + 65927 = 66006
  • 107 + 65899 = 66006
  • 139 + 65867 = 66006
  • 163 + 65843 = 66006
  • 167 + 65839 = 66006

Showing the first eight; more decompositions exist.
