Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142112, here are decompositions:
- 13 + 142099 = 142112
- 73 + 142039 = 142112
- 151 + 141961 = 142112
- 181 + 141931 = 142112
- 241 + 141871 = 142112
- 283 + 141829 = 142112
- 433 + 141679 = 142112
- 463 + 141649 = 142112
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 142,112 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
