Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111242, here are decompositions:
- 13 + 111229 = 111242
- 31 + 111211 = 111242
- 139 + 111103 = 111242
- 151 + 111091 = 111242
- 193 + 111049 = 111242
- 199 + 111043 = 111242
- 211 + 111031 = 111242
- 379 + 110863 = 111242
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 111,242 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
