Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525120, here are decompositions:

19 + 525101 = 525120
103 + 525017 = 525120
107 + 525013 = 525120
137 + 524983 = 525120
139 + 524981 = 525120
149 + 524971 = 525120
151 + 524969 = 525120
157 + 524963 = 525120

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 525,120 and was likely granted around 1894.

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