Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24138, here are decompositions:
- 5 + 24133 = 24138
- 17 + 24121 = 24138
- 29 + 24109 = 24138
- 31 + 24107 = 24138
- 41 + 24097 = 24138
- 47 + 24091 = 24138
- 61 + 24077 = 24138
- 67 + 24071 = 24138
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 24138 first appears in π at position 1,965 of the decimal expansion (the 1,965ordinal-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.
