Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 467840, here are decompositions:
- 7 + 467833 = 467840
- 13 + 467827 = 467840
- 67 + 467773 = 467840
- 97 + 467743 = 467840
- 103 + 467737 = 467840
- 127 + 467713 = 467840
- 151 + 467689 = 467840
- 199 + 467641 = 467840
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 467,840 and was likely granted around 1891.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
