Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515016, here are decompositions:

67 + 514949 = 515016
83 + 514933 = 515016
113 + 514903 = 515016
127 + 514889 = 515016
149 + 514867 = 515016
157 + 514859 = 515016
163 + 514853 = 515016
193 + 514823 = 515016

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 515,016 and was likely granted around 1894.

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