Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551108, here are decompositions:

139 + 550969 = 551108
157 + 550951 = 551108
199 + 550909 = 551108
277 + 550831 = 551108
307 + 550801 = 551108
457 + 550651 = 551108
487 + 550621 = 551108
499 + 550609 = 551108

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 551,108 and was likely granted around 1895.

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