Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557506, here are decompositions:

17 + 557489 = 557506
23 + 557483 = 557506
83 + 557423 = 557506
137 + 557369 = 557506
167 + 557339 = 557506
197 + 557309 = 557506
233 + 557273 = 557506
347 + 557159 = 557506

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 557,506 and was likely granted around 1895.

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