Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105442, here are decompositions:
- 5 + 105437 = 105442
- 41 + 105401 = 105442
- 53 + 105389 = 105442
- 83 + 105359 = 105442
- 101 + 105341 = 105442
- 173 + 105269 = 105442
- 179 + 105263 = 105442
- 191 + 105251 = 105442
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.155.226.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105.442 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.
