Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118142, here are decompositions:
- 61 + 118081 = 118142
- 109 + 118033 = 118142
- 151 + 117991 = 118142
- 163 + 117979 = 118142
- 331 + 117811 = 118142
- 379 + 117763 = 118142
- 421 + 117721 = 118142
- 433 + 117709 = 118142
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 118,142 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
