Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585050, here are decompositions:

  • 17 + 31585033 = 31585050
  • 31 + 31585019 = 31585050
  • 83 + 31584967 = 31585050
  • 89 + 31584961 = 31585050
  • 97 + 31584953 = 31585050
  • 103 + 31584947 = 31585050
  • 149 + 31584901 = 31585050
  • 163 + 31584887 = 31585050

Showing the first eight; more decompositions exist.
