Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24840, here are decompositions:
- 19 + 24821 = 24840
- 31 + 24809 = 24840
- 41 + 24799 = 24840
- 47 + 24793 = 24840
- 59 + 24781 = 24840
- 73 + 24767 = 24840
- 107 + 24733 = 24840
- 131 + 24709 = 24840
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 24840 first appears in π at position 43,090 of the decimal expansion (the 43,090ordinal-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.
