Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561024, here are decompositions:

5 + 561019 = 561024
47 + 560977 = 561024
83 + 560941 = 561024
127 + 560897 = 561024
131 + 560893 = 561024
137 + 560887 = 561024
151 + 560873 = 561024
197 + 560827 = 561024

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 561,024 and was likely granted around 1895.

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