Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171000, here are decompositions:
- 29 + 170971 = 171000
- 43 + 170957 = 171000
- 47 + 170953 = 171000
- 73 + 170927 = 171000
- 79 + 170921 = 171000
- 101 + 170899 = 171000
- 113 + 170887 = 171000
- 127 + 170873 = 171000
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 171,000 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
