Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103664, here are decompositions:
- 7 + 103657 = 103664
- 13 + 103651 = 103664
- 73 + 103591 = 103664
- 97 + 103567 = 103664
- 103 + 103561 = 103664
- 181 + 103483 = 103664
- 193 + 103471 = 103664
- 241 + 103423 = 103664
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.148.240.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 103 664 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.
