Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544832, here are decompositions:

  • 5 + 31544827 = 31544832
  • 13 + 31544819 = 31544832
  • 61 + 31544771 = 31544832
  • 73 + 31544759 = 31544832
  • 83 + 31544749 = 31544832
  • 113 + 31544719 = 31544832
  • 271 + 31544561 = 31544832
  • 281 + 31544551 = 31544832

Showing the first eight; more decompositions exist.
