Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592800, here are decompositions:

  • 3 + 31592797 = 31592800
  • 53 + 31592747 = 31592800
  • 137 + 31592663 = 31592800
  • 149 + 31592651 = 31592800
  • 179 + 31592621 = 31592800
  • 233 + 31592567 = 31592800
  • 269 + 31592531 = 31592800
  • 311 + 31592489 = 31592800

Showing the first eight; more decompositions exist.
