Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006686, here are decompositions:

53 + 1006633 = 1006686
73 + 1006613 = 1006686
97 + 1006589 = 1006686
103 + 1006583 = 1006686
127 + 1006559 = 1006686
139 + 1006547 = 1006686
173 + 1006513 = 1006686
179 + 1006507 = 1006686

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 1,006,686 and was likely granted around 1911.

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