Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526724, here are decompositions:

  • 11 + 31526713 = 31526724
  • 107 + 31526617 = 31526724
  • 191 + 31526533 = 31526724
  • 197 + 31526527 = 31526724
  • 227 + 31526497 = 31526724
  • 293 + 31526431 = 31526724
  • 337 + 31526387 = 31526724
  • 353 + 31526371 = 31526724

Showing the first eight; more decompositions exist.
