Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005636, here are decompositions:

17 + 1005619 = 1005636
19 + 1005617 = 1005636
43 + 1005593 = 1005636
83 + 1005553 = 1005636
109 + 1005527 = 1005636
179 + 1005457 = 1005636
197 + 1005439 = 1005636
199 + 1005437 = 1005636

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 1,005,636 and was likely granted around 1911.

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