Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525220, here are decompositions:

11 + 525209 = 525220
29 + 525191 = 525220
53 + 525167 = 525220
83 + 525137 = 525220
191 + 525029 = 525220
239 + 524981 = 525220
251 + 524969 = 525220
257 + 524963 = 525220

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 525,220 and was likely granted around 1894.

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