Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005210, here are decompositions:

7 + 1005203 = 1005210
23 + 1005187 = 1005210
67 + 1005143 = 1005210
79 + 1005131 = 1005210
103 + 1005107 = 1005210
109 + 1005101 = 1005210
131 + 1005079 = 1005210
137 + 1005073 = 1005210

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 1,005,210 and was likely granted around 1911.

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