Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 194, here are decompositions:

  • 3 + 191 = 194
  • 13 + 181 = 194
  • 31 + 163 = 194
  • 37 + 157 = 194
  • 43 + 151 = 194
  • 67 + 127 = 194
  • 97 + 97 = 194

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.
