Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005670, here are decompositions:

23 + 1005647 = 1005670
53 + 1005617 = 1005670
89 + 1005581 = 1005670
167 + 1005503 = 1005670
233 + 1005437 = 1005670
257 + 1005413 = 1005670
311 + 1005359 = 1005670
353 + 1005317 = 1005670

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 1,005,670 and was likely granted around 1911.

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