Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142402, here are decompositions:
- 11 + 142391 = 142402
- 83 + 142319 = 142402
- 131 + 142271 = 142402
- 179 + 142223 = 142402
- 191 + 142211 = 142402
- 233 + 142169 = 142402
- 251 + 142151 = 142402
- 353 + 142049 = 142402
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 142,402 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
