Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162000, here are decompositions:
- 17 + 161983 = 162000
- 23 + 161977 = 162000
- 29 + 161971 = 162000
- 31 + 161969 = 162000
- 43 + 161957 = 162000
- 53 + 161947 = 162000
- 79 + 161921 = 162000
- 89 + 161911 = 162000
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 162,000 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
