Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12200, here are decompositions:

  • 3 + 12197 = 12200
  • 37 + 12163 = 12200
  • 43 + 12157 = 12200
  • 103 + 12097 = 12200
  • 127 + 12073 = 12200
  • 151 + 12049 = 12200
  • 157 + 12043 = 12200
  • 163 + 12037 = 12200

Showing the first eight; more decompositions exist.
