Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561564, here are decompositions:

5 + 561559 = 561564
11 + 561553 = 561564
13 + 561551 = 561564
43 + 561521 = 561564
103 + 561461 = 561564
191 + 561373 = 561564
197 + 561367 = 561564
251 + 561313 = 561564

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 561,564 and was likely granted around 1895.

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