Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561510, here are decompositions:

71 + 561439 = 561510
101 + 561409 = 561510
137 + 561373 = 561510
151 + 561359 = 561510
163 + 561347 = 561510
167 + 561343 = 561510
197 + 561313 = 561510
233 + 561277 = 561510

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 561,510 and was likely granted around 1895.

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