Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551056, here are decompositions:

17 + 551039 = 551056
29 + 551027 = 551056
53 + 551003 = 551056
59 + 550997 = 551056
83 + 550973 = 551056
197 + 550859 = 551056
293 + 550763 = 551056
353 + 550703 = 551056

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 551,056 and was likely granted around 1895.

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