Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550306, here are decompositions:

17 + 550289 = 550306
23 + 550283 = 550306
137 + 550169 = 550306
167 + 550139 = 550306
179 + 550127 = 550306
233 + 550073 = 550306
257 + 550049 = 550306
443 + 549863 = 550306

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 550,306 and was likely granted around 1895.

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