Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461350, here are decompositions:

  • 7 + 31461343 = 31461350
  • 97 + 31461253 = 31461350
  • 127 + 31461223 = 31461350
  • 157 + 31461193 = 31461350
  • 223 + 31461127 = 31461350
  • 313 + 31461037 = 31461350
  • 337 + 31461013 = 31461350
  • 373 + 31460977 = 31461350

Showing the first eight; more decompositions exist.
