Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555154, here are decompositions:

11 + 555143 = 555154
71 + 555083 = 555154
101 + 555053 = 555154
113 + 555041 = 555154
227 + 554927 = 555154
263 + 554891 = 555154
311 + 554843 = 555154
317 + 554837 = 555154

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 555,154 and was likely granted around 1895.

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