Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162006, here are decompositions:

7 + 161999 = 162006
23 + 161983 = 162006
29 + 161977 = 162006
37 + 161969 = 162006
59 + 161947 = 162006
83 + 161923 = 162006
127 + 161879 = 162006
137 + 161869 = 162006

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 162,006 and was likely granted around 1874.

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