Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 463440, here are decompositions:
- 7 + 463433 = 463440
- 41 + 463399 = 463440
- 53 + 463387 = 463440
- 97 + 463343 = 463440
- 101 + 463339 = 463440
- 127 + 463313 = 463440
- 137 + 463303 = 463440
- 149 + 463291 = 463440
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 463,440 and was likely granted around 1891.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
