Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531000, here are decompositions:

11 + 530989 = 531000
17 + 530983 = 531000
23 + 530977 = 531000
31 + 530969 = 531000
53 + 530947 = 531000
89 + 530911 = 531000
103 + 530897 = 531000
131 + 530869 = 531000

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 531,000 and was likely granted around 1894.

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