Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000786, here are decompositions:

23 + 1000763 = 1000786
89 + 1000697 = 1000786
107 + 1000679 = 1000786
167 + 1000619 = 1000786
197 + 1000589 = 1000786
239 + 1000547 = 1000786
359 + 1000427 = 1000786
383 + 1000403 = 1000786

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 1,000,786 and was likely granted around 1911.

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