Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13806, here are decompositions:

  • 7 + 13799 = 13806
  • 17 + 13789 = 13806
  • 43 + 13763 = 13806
  • 47 + 13759 = 13806
  • 83 + 13723 = 13806
  • 97 + 13709 = 13806
  • 109 + 13697 = 13806
  • 113 + 13693 = 13806

Showing the first eight; more decompositions exist.

Possible US bank routing number

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.

Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
