Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517200, here are decompositions:

11 + 517189 = 517200
17 + 517183 = 517200
23 + 517177 = 517200
31 + 517169 = 517200
71 + 517129 = 517200
109 + 517091 = 517200
113 + 517087 = 517200
127 + 517073 = 517200

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 517,200 and was likely granted around 1894.

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