Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598032, here are decompositions:

  • 3 + 31598029 = 31598032
  • 5 + 31598027 = 31598032
  • 23 + 31598009 = 31598032
  • 71 + 31597961 = 31598032
  • 239 + 31597793 = 31598032
  • 269 + 31597763 = 31598032
  • 293 + 31597739 = 31598032
  • 311 + 31597721 = 31598032

Showing the first eight; more decompositions exist.
