Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525400, here are decompositions:

3 + 525397 = 525400
23 + 525377 = 525400
41 + 525359 = 525400
47 + 525353 = 525400
101 + 525299 = 525400
179 + 525221 = 525400
191 + 525209 = 525400
233 + 525167 = 525400

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 525,400 and was likely granted around 1894.

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