Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521464, here are decompositions:

17 + 521447 = 521464
71 + 521393 = 521464
101 + 521363 = 521464
107 + 521357 = 521464
197 + 521267 = 521464
233 + 521231 = 521464
263 + 521201 = 521464
311 + 521153 = 521464

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 521,464 and was likely granted around 1894.

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