Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472224, here are decompositions:

  • 23 + 31472201 = 31472224
  • 41 + 31472183 = 31472224
  • 71 + 31472153 = 31472224
  • 101 + 31472123 = 31472224
  • 233 + 31471991 = 31472224
  • 257 + 31471967 = 31472224
  • 317 + 31471907 = 31472224
  • 401 + 31471823 = 31472224

Showing the first eight; more decompositions exist.
