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.

Unspecified address (0.0.0.0/8) — "this network" placeholder.
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.
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.
