Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551300, here are decompositions:

3 + 551297 = 551300
19 + 551281 = 551300
31 + 551269 = 551300
67 + 551233 = 551300
103 + 551197 = 551300
157 + 551143 = 551300
193 + 551107 = 551300
241 + 551059 = 551300

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 551,300 and was likely granted around 1895.

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