Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104728, here are decompositions:
- 5 + 104723 = 104728
- 11 + 104717 = 104728
- 17 + 104711 = 104728
- 47 + 104681 = 104728
- 89 + 104639 = 104728
- 131 + 104597 = 104728
- 149 + 104579 = 104728
- 167 + 104561 = 104728
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.153.24.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 104.728 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.
