Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521230, here are decompositions:

29 + 521201 = 521230
53 + 521177 = 521230
167 + 521063 = 521230
179 + 521051 = 521230
191 + 521039 = 521230
263 + 520967 = 521230
317 + 520913 = 521230
389 + 520841 = 521230

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 521,230 and was likely granted around 1894.

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