Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105468, here are decompositions:
- 19 + 105449 = 105468
- 31 + 105437 = 105468
- 61 + 105407 = 105468
- 67 + 105401 = 105468
- 71 + 105397 = 105468
- 79 + 105389 = 105468
- 89 + 105379 = 105468
- 101 + 105367 = 105468
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.155.252.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105 468 and was likely granted around 1870.
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.
