Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550018, here are decompositions:

11 + 550007 = 550018
41 + 549977 = 550018
107 + 549911 = 550018
179 + 549839 = 550018
251 + 549767 = 550018
269 + 549749 = 550018
281 + 549737 = 550018
311 + 549707 = 550018

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 550,018 and was likely granted around 1895.

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