Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473600, here are decompositions:

  • 7 + 31473593 = 31473600
  • 17 + 31473583 = 31473600
  • 19 + 31473581 = 31473600
  • 71 + 31473529 = 31473600
  • 113 + 31473487 = 31473600
  • 163 + 31473437 = 31473600
  • 241 + 31473359 = 31473600
  • 269 + 31473331 = 31473600

Showing the first eight; more decompositions exist.
