Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148142, here are decompositions:
- 3 + 148139 = 148142
- 19 + 148123 = 148142
- 79 + 148063 = 148142
- 193 + 147949 = 148142
- 223 + 147919 = 148142
- 283 + 147859 = 148142
- 331 + 147811 = 148142
- 349 + 147793 = 148142
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 148,142 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
