Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555100, here are decompositions:

3 + 555097 = 555100
17 + 555083 = 555100
23 + 555077 = 555100
47 + 555053 = 555100
59 + 555041 = 555100
71 + 555029 = 555100
131 + 554969 = 555100
149 + 554951 = 555100

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 555,100 and was likely granted around 1895.

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