Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539058, here are decompositions:

  • 11 + 31539047 = 31539058
  • 71 + 31538987 = 31539058
  • 107 + 31538951 = 31539058
  • 251 + 31538807 = 31539058
  • 269 + 31538789 = 31539058
  • 347 + 31538711 = 31539058
  • 479 + 31538579 = 31539058
  • 569 + 31538489 = 31539058

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.

Federal Reserve
Federal Reserve district 3 (Philadelphia)

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