Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112042, here are decompositions:
- 11 + 112031 = 112042
- 23 + 112019 = 112042
- 83 + 111959 = 112042
- 89 + 111953 = 112042
- 149 + 111893 = 112042
- 173 + 111869 = 112042
- 179 + 111863 = 112042
- 251 + 111791 = 112042
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 112,042 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
