Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104980, here are decompositions:
- 47 + 104933 = 104980
- 89 + 104891 = 104980
- 101 + 104879 = 104980
- 131 + 104849 = 104980
- 149 + 104831 = 104980
- 179 + 104801 = 104980
- 191 + 104789 = 104980
- 251 + 104729 = 104980
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.154.20.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 104,980 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.
