Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550320, here are decompositions:

11 + 550309 = 550320
31 + 550289 = 550320
37 + 550283 = 550320
41 + 550279 = 550320
53 + 550267 = 550320
79 + 550241 = 550320
107 + 550213 = 550320
109 + 550211 = 550320

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 550,320 and was likely granted around 1895.

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