Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105264, here are decompositions:
- 11 + 105253 = 105264
- 13 + 105251 = 105264
- 37 + 105227 = 105264
- 53 + 105211 = 105264
- 97 + 105167 = 105264
- 127 + 105137 = 105264
- 157 + 105107 = 105264
- 167 + 105097 = 105264
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.155.48.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105,264 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.
