Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525310, here are decompositions:

11 + 525299 = 525310
53 + 525257 = 525310
89 + 525221 = 525310
101 + 525209 = 525310
167 + 525143 = 525310
173 + 525137 = 525310
281 + 525029 = 525310
293 + 525017 = 525310

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 525,310 and was likely granted around 1894.

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