Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525130, here are decompositions:

3 + 525127 = 525130
29 + 525101 = 525130
101 + 525029 = 525130
113 + 525017 = 525130
131 + 524999 = 525130
149 + 524981 = 525130
167 + 524963 = 525130
173 + 524957 = 525130

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 525,130 and was likely granted around 1894.

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