Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169140, here are decompositions:

11 + 169129 = 169140
29 + 169111 = 169140
43 + 169097 = 169140
47 + 169093 = 169140
61 + 169079 = 169140
71 + 169069 = 169140
73 + 169067 = 169140
131 + 169009 = 169140

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 169,140 and was likely granted around 1874.

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