Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001568, here are decompositions:

5 + 1001563 = 1001568
17 + 1001551 = 1001568
19 + 1001549 = 1001568
37 + 1001531 = 1001568
41 + 1001527 = 1001568
67 + 1001501 = 1001568
101 + 1001467 = 1001568
109 + 1001459 = 1001568

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 1,001,568 and was likely granted around 1911.

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