Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42356, here are decompositions:
- 7 + 42349 = 42356
- 19 + 42337 = 42356
- 73 + 42283 = 42356
- 163 + 42193 = 42356
- 199 + 42157 = 42356
- 283 + 42073 = 42356
- 313 + 42043 = 42356
- 337 + 42019 = 42356
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 42356 first appears in π at position 172,885 of the decimal expansion (the 172,885ordinal-suffix:th 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.
