Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169154, here are decompositions:

3 + 169151 = 169154
43 + 169111 = 169154
61 + 169093 = 169154
151 + 169003 = 169154
163 + 168991 = 169154
211 + 168943 = 169154
241 + 168913 = 169154
373 + 168781 = 169154

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 169,154 and was likely granted around 1874.

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