Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511250, here are decompositions:

7 + 511243 = 511250
13 + 511237 = 511250
37 + 511213 = 511250
73 + 511177 = 511250
79 + 511171 = 511250
97 + 511153 = 511250
127 + 511123 = 511250
139 + 511111 = 511250

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 511,250 and was likely granted around 1893.

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