Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491056, here are decompositions:

17 + 491039 = 491056
53 + 491003 = 491056
89 + 490967 = 491056
107 + 490949 = 491056
179 + 490877 = 491056
197 + 490859 = 491056
227 + 490829 = 491056
359 + 490697 = 491056

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 491,056 and was likely granted around 1892.

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