Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100842, here are decompositions:
- 13 + 100829 = 100842
- 19 + 100823 = 100842
- 31 + 100811 = 100842
- 41 + 100801 = 100842
- 43 + 100799 = 100842
- 73 + 100769 = 100842
- 101 + 100741 = 100842
- 109 + 100733 = 100842
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 100,842 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
