Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515026, here are decompositions:

59 + 514967 = 515026
137 + 514889 = 515026
167 + 514859 = 515026
173 + 514853 = 515026
179 + 514847 = 515026
233 + 514793 = 515026
257 + 514769 = 515026
269 + 514757 = 515026

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 515,026 and was likely granted around 1894.

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