Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600306, here are decompositions:

  • 5 + 31600301 = 31600306
  • 29 + 31600277 = 31600306
  • 47 + 31600259 = 31600306
  • 113 + 31600193 = 31600306
  • 149 + 31600157 = 31600306
  • 173 + 31600133 = 31600306
  • 263 + 31600043 = 31600306
  • 347 + 31599959 = 31600306

Showing the first eight; more decompositions exist.
