Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038638, here are decompositions:

19 + 1038619 = 1038638
37 + 1038601 = 1038638
109 + 1038529 = 1038638
151 + 1038487 = 1038638
229 + 1038409 = 1038638
331 + 1038307 = 1038638
379 + 1038259 = 1038638
439 + 1038199 = 1038638

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 1,038,638 and was likely granted around 1912.

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