Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 462640, here are decompositions:
- 11 + 462629 = 462640
- 71 + 462569 = 462640
- 83 + 462557 = 462640
- 149 + 462491 = 462640
- 173 + 462467 = 462640
- 197 + 462443 = 462640
- 239 + 462401 = 462640
- 263 + 462377 = 462640
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 462,640 and was likely granted around 1891.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
