Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001648, here are decompositions:

19 + 1001629 = 1001648
61 + 1001587 = 1001648
79 + 1001569 = 1001648
97 + 1001551 = 1001648
157 + 1001491 = 1001648
181 + 1001467 = 1001648
337 + 1001311 = 1001648
457 + 1001191 = 1001648

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 1,001,648 and was likely granted around 1911.

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