Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000638, here are decompositions:

17 + 1000621 = 1000638
19 + 1000619 = 1000638
29 + 1000609 = 1000638
59 + 1000579 = 1000638
61 + 1000577 = 1000638
97 + 1000541 = 1000638
101 + 1000537 = 1000638
131 + 1000507 = 1000638

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 1,000,638 and was likely granted around 1911.

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