Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55200, here are decompositions:

  • 29 + 55171 = 55200
  • 37 + 55163 = 55200
  • 53 + 55147 = 55200
  • 73 + 55127 = 55200
  • 83 + 55117 = 55200
  • 97 + 55103 = 55200
  • 127 + 55073 = 55200
  • 139 + 55061 = 55200

Showing the first eight; more decompositions exist.
