Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551020, here are decompositions:

3 + 551017 = 551020
17 + 551003 = 551020
23 + 550997 = 551020
47 + 550973 = 551020
59 + 550961 = 551020
83 + 550937 = 551020
179 + 550841 = 551020
257 + 550763 = 551020

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 551,020 and was likely granted around 1895.

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