Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30400, here are decompositions:

  • 11 + 30389 = 30400
  • 53 + 30347 = 30400
  • 59 + 30341 = 30400
  • 107 + 30293 = 30400
  • 131 + 30269 = 30400
  • 197 + 30203 = 30400
  • 239 + 30161 = 30400
  • 263 + 30137 = 30400

Showing the first eight; more decompositions exist.
