Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102342, here are decompositions:
- 5 + 102337 = 102342
- 13 + 102329 = 102342
- 41 + 102301 = 102342
- 43 + 102299 = 102342
- 83 + 102259 = 102342
- 89 + 102253 = 102342
- 101 + 102241 = 102342
- 109 + 102233 = 102342
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 102,342 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
