Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505564, here are decompositions:

5 + 505559 = 505564
41 + 505523 = 505564
53 + 505511 = 505564
71 + 505493 = 505564
83 + 505481 = 505564
197 + 505367 = 505564
251 + 505313 = 505564
263 + 505301 = 505564

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 505,564 and was likely granted around 1893.

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