Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104842, here are decompositions:
- 11 + 104831 = 104842
- 41 + 104801 = 104842
- 53 + 104789 = 104842
- 83 + 104759 = 104842
- 113 + 104729 = 104842
- 131 + 104711 = 104842
- 149 + 104693 = 104842
- 191 + 104651 = 104842
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 104,842 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
