Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500856, here are decompositions:

17 + 500839 = 500856
47 + 500809 = 500856
79 + 500777 = 500856
127 + 500729 = 500856
137 + 500719 = 500856
157 + 500699 = 500856
163 + 500693 = 500856
179 + 500677 = 500856

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 500,856 and was likely granted around 1893.

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