Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558344, here are decompositions:

  • 7 + 31558337 = 31558344
  • 17 + 31558327 = 31558344
  • 23 + 31558321 = 31558344
  • 61 + 31558283 = 31558344
  • 137 + 31558207 = 31558344
  • 157 + 31558187 = 31558344
  • 163 + 31558181 = 31558344
  • 197 + 31558147 = 31558344

Showing the first eight; more decompositions exist.
