Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100828, here are decompositions:
- 5 + 100823 = 100828
- 17 + 100811 = 100828
- 29 + 100799 = 100828
- 41 + 100787 = 100828
- 59 + 100769 = 100828
- 179 + 100649 = 100828
- 269 + 100559 = 100828
- 281 + 100547 = 100828
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 100,828 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
