Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546912, here are decompositions:

  • 3 + 31546909 = 31546912
  • 113 + 31546799 = 31546912
  • 191 + 31546721 = 31546912
  • 251 + 31546661 = 31546912
  • 311 + 31546601 = 31546912
  • 359 + 31546553 = 31546912
  • 443 + 31546469 = 31546912
  • 461 + 31546451 = 31546912

Showing the first eight; more decompositions exist.
