Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11200, here are decompositions:

  • 3 + 11197 = 11200
  • 23 + 11177 = 11200
  • 29 + 11171 = 11200
  • 41 + 11159 = 11200
  • 83 + 11117 = 11200
  • 107 + 11093 = 11200
  • 113 + 11087 = 11200
  • 131 + 11069 = 11200

Showing the first eight; more decompositions exist.
