Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001688, here are decompositions:

5 + 1001683 = 1001688
19 + 1001669 = 1001688
29 + 1001659 = 1001688
59 + 1001629 = 1001688
67 + 1001621 = 1001688
101 + 1001587 = 1001688
137 + 1001551 = 1001688
139 + 1001549 = 1001688

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 1,001,688 and was likely granted around 1911.

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