Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530530, here are decompositions:

3 + 530527 = 530530
17 + 530513 = 530530
23 + 530507 = 530530
29 + 530501 = 530530
83 + 530447 = 530530
101 + 530429 = 530530
137 + 530393 = 530530
191 + 530339 = 530530

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 530,530 and was likely granted around 1894.

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