Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005400, here are decompositions:

29 + 1005371 = 1005400
41 + 1005359 = 1005400
83 + 1005317 = 1005400
107 + 1005293 = 1005400
113 + 1005287 = 1005400
131 + 1005269 = 1005400
191 + 1005209 = 1005400
197 + 1005203 = 1005400

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 1,005,400 and was likely granted around 1911.

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