Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166004, here are decompositions:

43 + 165961 = 166004
73 + 165931 = 166004
103 + 165901 = 166004
127 + 165877 = 166004
193 + 165811 = 166004
283 + 165721 = 166004
331 + 165673 = 166004
337 + 165667 = 166004

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 166,004 and was likely granted around 1874.

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