Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530220, here are decompositions:

11 + 530209 = 530220
17 + 530203 = 530220
23 + 530197 = 530220
37 + 530183 = 530220
43 + 530177 = 530220
83 + 530137 = 530220
127 + 530093 = 530220
157 + 530063 = 530220

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 530,220 and was likely granted around 1894.

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