Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530180, here are decompositions:

3 + 530177 = 530180
37 + 530143 = 530180
43 + 530137 = 530180
139 + 530041 = 530180
163 + 530017 = 530180
181 + 529999 = 530180
193 + 529987 = 530180
199 + 529981 = 530180

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 530,180 and was likely granted around 1894.

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