Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515030, here are decompositions:

97 + 514933 = 515030
127 + 514903 = 515030
157 + 514873 = 515030
163 + 514867 = 515030
199 + 514831 = 515030
211 + 514819 = 515030
283 + 514747 = 515030
349 + 514681 = 515030

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 515,030 and was likely granted around 1894.

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