Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530020, here are decompositions:

3 + 530017 = 530020
41 + 529979 = 530020
47 + 529973 = 530020
59 + 529961 = 530020
149 + 529871 = 530020
173 + 529847 = 530020
191 + 529829 = 530020
269 + 529751 = 530020

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 530,020 and was likely granted around 1894.

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