Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105342, here are decompositions:
- 5 + 105337 = 105342
- 11 + 105331 = 105342
- 19 + 105323 = 105342
- 23 + 105319 = 105342
- 73 + 105269 = 105342
- 79 + 105263 = 105342
- 89 + 105253 = 105342
- 103 + 105239 = 105342
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 105 342 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
