Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4400, here are decompositions:

  • 3 + 4397 = 4400
  • 37 + 4363 = 4400
  • 43 + 4357 = 4400
  • 61 + 4339 = 4400
  • 73 + 4327 = 4400
  • 103 + 4297 = 4400
  • 127 + 4273 = 4400
  • 139 + 4261 = 4400

Showing the first eight; more decompositions exist.
