Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142204, here are decompositions:
- 11 + 142193 = 142204
- 47 + 142157 = 142204
- 53 + 142151 = 142204
- 107 + 142097 = 142204
- 137 + 142067 = 142204
- 173 + 142031 = 142204
- 197 + 142007 = 142204
- 233 + 141971 = 142204
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 142,204 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
