Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550900, here are decompositions:

41 + 550859 = 550900
59 + 550841 = 550900
89 + 550811 = 550900
137 + 550763 = 550900
167 + 550733 = 550900
179 + 550721 = 550900
197 + 550703 = 550900
239 + 550661 = 550900

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 550,900 and was likely granted around 1895.

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