Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551306, here are decompositions:

37 + 551269 = 551306
73 + 551233 = 551306
109 + 551197 = 551306
127 + 551179 = 551306
163 + 551143 = 551306
193 + 551113 = 551306
199 + 551107 = 551306
313 + 550993 = 551306

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 551,306 and was likely granted around 1895.

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