Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501250, here are decompositions:

17 + 501233 = 501250
41 + 501209 = 501250
47 + 501203 = 501250
53 + 501197 = 501250
59 + 501191 = 501250
173 + 501077 = 501250
293 + 500957 = 501250
317 + 500933 = 501250

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 501,250 and was likely granted around 1893.

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