Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115442, here are decompositions:
- 13 + 115429 = 115442
- 43 + 115399 = 115442
- 79 + 115363 = 115442
- 139 + 115303 = 115442
- 163 + 115279 = 115442
- 193 + 115249 = 115442
- 241 + 115201 = 115442
- 421 + 115021 = 115442
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 115,442 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
