Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001566, here are decompositions:

3 + 1001563 = 1001566
17 + 1001549 = 1001566
107 + 1001459 = 1001566
179 + 1001387 = 1001566
197 + 1001369 = 1001566
239 + 1001327 = 1001566
263 + 1001303 = 1001566
347 + 1001219 = 1001566

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 1,001,566 and was likely granted around 1911.

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