Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491100, here are decompositions:

17 + 491083 = 491100
19 + 491081 = 491100
41 + 491059 = 491100
59 + 491041 = 491100
61 + 491039 = 491100
97 + 491003 = 491100
107 + 490993 = 491100
109 + 490991 = 491100

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 491,100 and was likely granted around 1892.

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