Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531510, here are decompositions:

13 + 531497 = 531510
29 + 531481 = 531510
53 + 531457 = 531510
127 + 531383 = 531510
151 + 531359 = 531510
157 + 531353 = 531510
163 + 531347 = 531510
167 + 531343 = 531510

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 531,510 and was likely granted around 1894.

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