Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42424, here are decompositions:
- 17 + 42407 = 42424
- 101 + 42323 = 42424
- 131 + 42293 = 42424
- 167 + 42257 = 42424
- 197 + 42227 = 42424
- 227 + 42197 = 42424
- 293 + 42131 = 42424
- 353 + 42071 = 42424
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 42424 first appears in π at position 78,406 of the decimal expansion (the 78,406ordinal-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.
