Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169020, here are decompositions:

11 + 169009 = 169020
13 + 169007 = 169020
17 + 169003 = 169020
29 + 168991 = 169020
43 + 168977 = 169020
83 + 168937 = 169020
107 + 168913 = 169020
127 + 168893 = 169020

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 169,020 and was likely granted around 1874.

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