Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446344, here are decompositions:

  • 3 + 31446341 = 31446344
  • 103 + 31446241 = 31446344
  • 211 + 31446133 = 31446344
  • 277 + 31446067 = 31446344
  • 283 + 31446061 = 31446344
  • 313 + 31446031 = 31446344
  • 367 + 31445977 = 31446344
  • 733 + 31445611 = 31446344

Showing the first eight; more decompositions exist.
