Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510250, here are decompositions:

3 + 510247 = 510250
17 + 510233 = 510250
23 + 510227 = 510250
47 + 510203 = 510250
71 + 510179 = 510250
113 + 510137 = 510250
149 + 510101 = 510250
173 + 510077 = 510250

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 510,250 and was likely granted around 1893.

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