Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464400, here are decompositions:

  • 3 + 31464397 = 31464400
  • 41 + 31464359 = 31464400
  • 59 + 31464341 = 31464400
  • 131 + 31464269 = 31464400
  • 167 + 31464233 = 31464400
  • 251 + 31464149 = 31464400
  • 257 + 31464143 = 31464400
  • 263 + 31464137 = 31464400

Showing the first eight; more decompositions exist.
