Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108142, here are decompositions:
- 3 + 108139 = 108142
- 11 + 108131 = 108142
- 53 + 108089 = 108142
- 101 + 108041 = 108142
- 131 + 108011 = 108142
- 191 + 107951 = 108142
- 239 + 107903 = 108142
- 269 + 107873 = 108142
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 108,142 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
