Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87204, here are decompositions:

  • 17 + 87187 = 87204
  • 23 + 87181 = 87204
  • 53 + 87151 = 87204
  • 71 + 87133 = 87204
  • 83 + 87121 = 87204
  • 97 + 87107 = 87204
  • 101 + 87103 = 87204
  • 163 + 87041 = 87204

Showing the first eight; more decompositions exist.
