Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005080, here are decompositions:

7 + 1005073 = 1005080
31 + 1005049 = 1005080
61 + 1005019 = 1005080
67 + 1005013 = 1005080
73 + 1005007 = 1005080
103 + 1004977 = 1005080
163 + 1004917 = 1005080
283 + 1004797 = 1005080

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 1,005,080 and was likely granted around 1911.

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