Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105248, here are decompositions:
- 19 + 105229 = 105248
- 37 + 105211 = 105248
- 151 + 105097 = 105248
- 211 + 105037 = 105248
- 229 + 105019 = 105248
- 277 + 104971 = 105248
- 331 + 104917 = 105248
- 337 + 104911 = 105248
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.155.32.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105.248 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.
