Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520210, here are decompositions:

17 + 520193 = 520210
59 + 520151 = 520210
107 + 520103 = 520210
137 + 520073 = 520210
167 + 520043 = 520210
179 + 520031 = 520210
191 + 520019 = 520210
239 + 519971 = 520210

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 520,210 and was likely granted around 1894.

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