Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550540, here are decompositions:

71 + 550469 = 550540
83 + 550457 = 550540
101 + 550439 = 550540
113 + 550427 = 550540
251 + 550289 = 550540
257 + 550283 = 550540
359 + 550181 = 550540
401 + 550139 = 550540

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 550,540 and was likely granted around 1895.

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