Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1724, here are decompositions:
- 3 + 1721 = 1724
- 31 + 1693 = 1724
- 61 + 1663 = 1724
- 67 + 1657 = 1724
- 97 + 1627 = 1724
- 103 + 1621 = 1724
- 127 + 1597 = 1724
- 157 + 1567 = 1724
Showing the first eight; more decompositions exist.

As an unsigned 32-bit integer, this is the IPv4 address 0.0.6.188.

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 1724 first appears in π at position 24,070 of the decimal expansion (the 24,070ordinal-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.
