Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7200, here are decompositions:

  • 7 + 7193 = 7200
  • 13 + 7187 = 7200
  • 23 + 7177 = 7200
  • 41 + 7159 = 7200
  • 71 + 7129 = 7200
  • 73 + 7127 = 7200
  • 79 + 7121 = 7200
  • 97 + 7103 = 7200

Showing the first eight; more decompositions exist.
