Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515456, here are decompositions:

79 + 515377 = 515456
163 + 515293 = 515456
223 + 515233 = 515456
229 + 515227 = 515456
283 + 515173 = 515456
307 + 515149 = 515456
313 + 515143 = 515456
367 + 515089 = 515456

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 515,456 and was likely granted around 1894.

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