Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551016, here are decompositions:

13 + 551003 = 551016
19 + 550997 = 551016
23 + 550993 = 551016
43 + 550973 = 551016
47 + 550969 = 551016
79 + 550937 = 551016
107 + 550909 = 551016
113 + 550903 = 551016

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 551,016 and was likely granted around 1895.

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