Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454356, here are decompositions:

  • 5 + 31454351 = 31454356
  • 107 + 31454249 = 31454356
  • 137 + 31454219 = 31454356
  • 233 + 31454123 = 31454356
  • 239 + 31454117 = 31454356
  • 359 + 31453997 = 31454356
  • 677 + 31453679 = 31454356
  • 827 + 31453529 = 31454356

Showing the first eight; more decompositions exist.
