Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447266, here are decompositions:

  • 13 + 31447253 = 31447266
  • 163 + 31447103 = 31447266
  • 167 + 31447099 = 31447266
  • 197 + 31447069 = 31447266
  • 223 + 31447043 = 31447266
  • 239 + 31447027 = 31447266
  • 269 + 31446997 = 31447266
  • 283 + 31446983 = 31447266

Showing the first eight; more decompositions exist.
