Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159170, here are decompositions:
- 3 + 159167 = 159170
- 13 + 159157 = 159170
- 73 + 159097 = 159170
- 97 + 159073 = 159170
- 157 + 159013 = 159170
- 211 + 158959 = 159170
- 229 + 158941 = 159170
- 307 + 158863 = 159170
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 159,170 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
