Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530320, here are decompositions:

17 + 530303 = 530320
23 + 530297 = 530320
41 + 530279 = 530320
53 + 530267 = 530320
59 + 530261 = 530320
71 + 530249 = 530320
83 + 530237 = 530320
137 + 530183 = 530320

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 530,320 and was likely granted around 1894.

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