Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142202, here are decompositions:
- 13 + 142189 = 142202
- 19 + 142183 = 142202
- 43 + 142159 = 142202
- 79 + 142123 = 142202
- 103 + 142099 = 142202
- 163 + 142039 = 142202
- 211 + 141991 = 142202
- 241 + 141961 = 142202
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 142,202 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
