Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133142, here are decompositions:
- 73 + 133069 = 133142
- 103 + 133039 = 133142
- 109 + 133033 = 133142
- 181 + 132961 = 133142
- 193 + 132949 = 133142
- 283 + 132859 = 133142
- 379 + 132763 = 133142
- 421 + 132721 = 133142
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 133,142 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
