Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031648, here are decompositions:

19 + 1031629 = 1031648
127 + 1031521 = 1031648
349 + 1031299 = 1031648
367 + 1031281 = 1031648
487 + 1031161 = 1031648
601 + 1031047 = 1031648
661 + 1030987 = 1031648
691 + 1030957 = 1031648

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 1,031,648 and was likely granted around 1912.

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