Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 200, here are decompositions:

  • 3 + 197 = 200
  • 7 + 193 = 200
  • 19 + 181 = 200
  • 37 + 163 = 200
  • 43 + 157 = 200
  • 61 + 139 = 200
  • 73 + 127 = 200
  • 97 + 103 = 200

Showing the first eight; more decompositions exist.
