Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005556, here are decompositions:

3 + 1005553 = 1005556
5 + 1005551 = 1005556
29 + 1005527 = 1005556
53 + 1005503 = 1005556
89 + 1005467 = 1005556
197 + 1005359 = 1005556
239 + 1005317 = 1005556
263 + 1005293 = 1005556

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 1,005,556 and was likely granted around 1911.

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