Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481000, here are decompositions:
- 11 + 480989 = 481000
- 41 + 480959 = 481000
- 59 + 480941 = 481000
- 71 + 480929 = 481000
- 89 + 480911 = 481000
- 173 + 480827 = 481000
- 197 + 480803 = 481000
- 227 + 480773 = 481000
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 481,000 and was likely granted around 1892.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
