Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169120, here are decompositions:

23 + 169097 = 169120
41 + 169079 = 169120
53 + 169067 = 169120
71 + 169049 = 169120
101 + 169019 = 169120
113 + 169007 = 169120
227 + 168893 = 169120
233 + 168887 = 169120

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 169,120 and was likely granted around 1874.

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