Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599958, here are decompositions:

  • 17 + 31599941 = 31599958
  • 29 + 31599929 = 31599958
  • 41 + 31599917 = 31599958
  • 149 + 31599809 = 31599958
  • 191 + 31599767 = 31599958
  • 197 + 31599761 = 31599958
  • 251 + 31599707 = 31599958
  • 347 + 31599611 = 31599958

Showing the first eight; more decompositions exist.
