Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88400, here are decompositions:

  • 3 + 88397 = 88400
  • 61 + 88339 = 88400
  • 73 + 88327 = 88400
  • 79 + 88321 = 88400
  • 139 + 88261 = 88400
  • 163 + 88237 = 88400
  • 223 + 88177 = 88400
  • 271 + 88129 = 88400

Showing the first eight; more decompositions exist.
