Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108724, here are decompositions:
- 17 + 108707 = 108724
- 47 + 108677 = 108724
- 137 + 108587 = 108724
- 167 + 108557 = 108724
- 191 + 108533 = 108724
- 227 + 108497 = 108724
- 263 + 108461 = 108724
- 311 + 108413 = 108724
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.168.180.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 108,724 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
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 108724 first appears in π at position 972,180 of the decimal expansion (the 972,180ordinal-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.
