Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563832, here are decompositions:

  • 5 + 31563827 = 31563832
  • 59 + 31563773 = 31563832
  • 149 + 31563683 = 31563832
  • 239 + 31563593 = 31563832
  • 263 + 31563569 = 31563832
  • 281 + 31563551 = 31563832
  • 389 + 31563443 = 31563832
  • 401 + 31563431 = 31563832

Showing the first eight; more decompositions exist.
