Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142342, here are decompositions:
- 23 + 142319 = 142342
- 71 + 142271 = 142342
- 131 + 142211 = 142342
- 149 + 142193 = 142342
- 173 + 142169 = 142342
- 191 + 142151 = 142342
- 281 + 142061 = 142342
- 293 + 142049 = 142342
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 142,342 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
