Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23456, here are decompositions:

  • 163 + 23293 = 23456
  • 229 + 23227 = 23456
  • 283 + 23173 = 23456
  • 313 + 23143 = 23456
  • 397 + 23059 = 23456
  • 439 + 23017 = 23456
  • 463 + 22993 = 23456
  • 673 + 22783 = 23456

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.

Position in π

The digit sequence 23456 first appears in π at position 80,982 of the decimal expansion (the 80,982ordinal-suffix:nd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
