Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13172, here are decompositions:

  • 13 + 13159 = 13172
  • 73 + 13099 = 13172
  • 79 + 13093 = 13172
  • 109 + 13063 = 13172
  • 139 + 13033 = 13172
  • 163 + 13009 = 13172
  • 193 + 12979 = 13172
  • 199 + 12973 = 13172

Showing the first eight; more decompositions exist.
