Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550144, here are decompositions:

5 + 550139 = 550144
17 + 550127 = 550144
71 + 550073 = 550144
83 + 550061 = 550144
137 + 550007 = 550144
167 + 549977 = 550144
233 + 549911 = 550144
281 + 549863 = 550144

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 550,144 and was likely granted around 1895.

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