Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169000, here are decompositions:

23 + 168977 = 169000
101 + 168899 = 169000
107 + 168893 = 169000
113 + 168887 = 169000
131 + 168869 = 169000
137 + 168863 = 169000
149 + 168851 = 169000
197 + 168803 = 169000

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 169,000 and was likely granted around 1874.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
