Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520180, here are decompositions:

29 + 520151 = 520180
107 + 520073 = 520180
113 + 520067 = 520180
137 + 520043 = 520180
149 + 520031 = 520180
191 + 519989 = 520180
233 + 519947 = 520180
257 + 519923 = 520180

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 520,180 and was likely granted around 1894.

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