Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561364, here are decompositions:

5 + 561359 = 561364
17 + 561347 = 561364
113 + 561251 = 561364
173 + 561191 = 561364
191 + 561173 = 561364
263 + 561101 = 561364
281 + 561083 = 561364
311 + 561053 = 561364

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 561,364 and was likely granted around 1895.

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