Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481664, here are decompositions:
- 13 + 481651 = 481664
- 31 + 481633 = 481664
- 151 + 481513 = 481664
- 163 + 481501 = 481664
- 277 + 481387 = 481664
- 367 + 481297 = 481664
- 433 + 481231 = 481664
- 457 + 481207 = 481664
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 481,664 and was likely granted around 1892.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
