Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530720, here are decompositions:

7 + 530713 = 530720
19 + 530701 = 530720
61 + 530659 = 530720
67 + 530653 = 530720
79 + 530641 = 530720
181 + 530539 = 530720
193 + 530527 = 530720
277 + 530443 = 530720

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 530,720 and was likely granted around 1894.

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