Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169100, here are decompositions:
- 3 + 169097 = 169100
- 7 + 169093 = 169100
- 31 + 169069 = 169100
- 37 + 169063 = 169100
- 97 + 169003 = 169100
- 109 + 168991 = 169100
- 157 + 168943 = 169100
- 163 + 168937 = 169100
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 169,100 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
