Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555800, here are decompositions:

61 + 555739 = 555800
103 + 555697 = 555800
109 + 555691 = 555800
139 + 555661 = 555800
163 + 555637 = 555800
211 + 555589 = 555800
277 + 555523 = 555800
313 + 555487 = 555800

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 555,800 and was likely granted around 1895.

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