Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531700, here are decompositions:

11 + 531689 = 531700
89 + 531611 = 531700
131 + 531569 = 531700
149 + 531551 = 531700
179 + 531521 = 531700
317 + 531383 = 531700
347 + 531353 = 531700
353 + 531347 = 531700

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 531,700 and was likely granted around 1894.

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