Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1041866, here are decompositions:

3 + 1041863 = 1041866
13 + 1041853 = 1041866
37 + 1041829 = 1041866
43 + 1041823 = 1041866
73 + 1041793 = 1041866
79 + 1041787 = 1041866
109 + 1041757 = 1041866
193 + 1041673 = 1041866

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 1,041,866 and was likely granted around 1912.

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