Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100822, here are decompositions:
- 11 + 100811 = 100822
- 23 + 100799 = 100822
- 53 + 100769 = 100822
- 89 + 100733 = 100822
- 149 + 100673 = 100822
- 173 + 100649 = 100822
- 263 + 100559 = 100822
- 311 + 100511 = 100822
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 100,822 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
