Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1061866, here are decompositions:

17 + 1061849 = 1061866
59 + 1061807 = 1061866
83 + 1061783 = 1061866
107 + 1061759 = 1061866
137 + 1061729 = 1061866
149 + 1061717 = 1061866
167 + 1061699 = 1061866
257 + 1061609 = 1061866

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 1,061,866 and was likely granted around 1912.

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