Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000858, here are decompositions:

11 + 1000847 = 1000858
29 + 1000829 = 1000858
137 + 1000721 = 1000858
167 + 1000691 = 1000858
179 + 1000679 = 1000858
191 + 1000667 = 1000858
239 + 1000619 = 1000858
269 + 1000589 = 1000858

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 1,000,858 and was likely granted around 1911.

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