Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460272, here are decompositions:

  • 5 + 31460267 = 31460272
  • 419 + 31459853 = 31460272
  • 443 + 31459829 = 31460272
  • 563 + 31459709 = 31460272
  • 593 + 31459679 = 31460272
  • 653 + 31459619 = 31460272
  • 719 + 31459553 = 31460272
  • 773 + 31459499 = 31460272

Showing the first eight; more decompositions exist.
