Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526582, here are decompositions:

  • 19 + 31526563 = 31526582
  • 79 + 31526503 = 31526582
  • 151 + 31526431 = 31526582
  • 163 + 31526419 = 31526582
  • 193 + 31526389 = 31526582
  • 211 + 31526371 = 31526582
  • 223 + 31526359 = 31526582
  • 499 + 31526083 = 31526582

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.

Routing number
031526582
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.
