Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561000, here are decompositions:

23 + 560977 = 561000
31 + 560969 = 561000
59 + 560941 = 561000
61 + 560939 = 561000
71 + 560929 = 561000
103 + 560897 = 561000
107 + 560893 = 561000
109 + 560891 = 561000

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 561,000 and was likely granted around 1895.

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