Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544928, here are decompositions:

  • 5 + 31544923 = 31544928
  • 29 + 31544899 = 31544928
  • 71 + 31544857 = 31544928
  • 101 + 31544827 = 31544928
  • 109 + 31544819 = 31544928
  • 157 + 31544771 = 31544928
  • 179 + 31544749 = 31544928
  • 211 + 31544717 = 31544928

Showing the first eight; more decompositions exist.
