Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526250, here are decompositions:

19 + 526231 = 526250
37 + 526213 = 526250
61 + 526189 = 526250
163 + 526087 = 526250
181 + 526069 = 526250
199 + 526051 = 526250
223 + 526027 = 526250
271 + 525979 = 526250

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 526,250 and was likely granted around 1894.

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