Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599170, here are decompositions:

  • 13 + 31599157 = 31599170
  • 67 + 31599103 = 31599170
  • 181 + 31598989 = 31599170
  • 223 + 31598947 = 31599170
  • 283 + 31598887 = 31599170
  • 307 + 31598863 = 31599170
  • 313 + 31598857 = 31599170
  • 331 + 31598839 = 31599170

Showing the first eight; more decompositions exist.
