Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530500, here are decompositions:

53 + 530447 = 530500
71 + 530429 = 530500
107 + 530393 = 530500
167 + 530333 = 530500
197 + 530303 = 530500
233 + 530267 = 530500
239 + 530261 = 530500
251 + 530249 = 530500

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 530,500 and was likely granted around 1894.

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