Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585176, here are decompositions:

  • 5 + 31585171 = 31585176
  • 17 + 31585159 = 31585176
  • 37 + 31585139 = 31585176
  • 83 + 31585093 = 31585176
  • 97 + 31585079 = 31585176
  • 109 + 31585067 = 31585176
  • 157 + 31585019 = 31585176
  • 223 + 31584953 = 31585176

Showing the first eight; more decompositions exist.
