Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87154, here are decompositions:

  • 3 + 87151 = 87154
  • 5 + 87149 = 87154
  • 47 + 87107 = 87154
  • 71 + 87083 = 87154
  • 83 + 87071 = 87154
  • 113 + 87041 = 87154
  • 173 + 86981 = 87154
  • 227 + 86927 = 87154

Showing the first eight; more decompositions exist.
