Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515050, here are decompositions:

83 + 514967 = 515050
101 + 514949 = 515050
191 + 514859 = 515050
197 + 514853 = 515050
227 + 514823 = 515050
257 + 514793 = 515050
281 + 514769 = 515050
293 + 514757 = 515050

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 515,050 and was likely granted around 1894.

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