Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453834, here are decompositions:

  • 11 + 31453823 = 31453834
  • 101 + 31453733 = 31453834
  • 107 + 31453727 = 31453834
  • 257 + 31453577 = 31453834
  • 263 + 31453571 = 31453834
  • 311 + 31453523 = 31453834
  • 443 + 31453391 = 31453834
  • 593 + 31453241 = 31453834

Showing the first eight; more decompositions exist.
