Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457326, here are decompositions:

  • 23 + 31457303 = 31457326
  • 29 + 31457297 = 31457326
  • 59 + 31457267 = 31457326
  • 167 + 31457159 = 31457326
  • 227 + 31457099 = 31457326
  • 233 + 31457093 = 31457326
  • 317 + 31457009 = 31457326
  • 389 + 31456937 = 31457326

Showing the first eight; more decompositions exist.
