Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038860, here are decompositions:

37 + 1038823 = 1038860
103 + 1038757 = 1038860
139 + 1038721 = 1038860
223 + 1038637 = 1038860
241 + 1038619 = 1038860
271 + 1038589 = 1038860
331 + 1038529 = 1038860
337 + 1038523 = 1038860

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 1,038,860 and was likely granted around 1912.

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