Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545274, here are decompositions:

  • 41 + 31545233 = 31545274
  • 53 + 31545221 = 31545274
  • 83 + 31545191 = 31545274
  • 191 + 31545083 = 31545274
  • 251 + 31545023 = 31545274
  • 311 + 31544963 = 31545274
  • 491 + 31544783 = 31545274
  • 503 + 31544771 = 31545274

Showing the first eight; more decompositions exist.
