Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20242, here are decompositions:

  • 11 + 20231 = 20242
  • 23 + 20219 = 20242
  • 41 + 20201 = 20242
  • 59 + 20183 = 20242
  • 113 + 20129 = 20242
  • 179 + 20063 = 20242
  • 191 + 20051 = 20242
  • 251 + 19991 = 20242

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.
