Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005180, here are decompositions:

19 + 1005161 = 1005180
37 + 1005143 = 1005180
47 + 1005133 = 1005180
73 + 1005107 = 1005180
79 + 1005101 = 1005180
101 + 1005079 = 1005180
107 + 1005073 = 1005180
109 + 1005071 = 1005180

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 1,005,180 and was likely granted around 1911.

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