Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143162, here are decompositions:
- 3 + 143159 = 143162
- 109 + 143053 = 143162
- 181 + 142981 = 143162
- 193 + 142969 = 143162
- 199 + 142963 = 143162
- 223 + 142939 = 143162
- 373 + 142789 = 143162
- 463 + 142699 = 143162
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 143,162 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
