Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510750, here are decompositions:

41 + 510709 = 510750
43 + 510707 = 510750
59 + 510691 = 510750
67 + 510683 = 510750
73 + 510677 = 510750
131 + 510619 = 510750
137 + 510613 = 510750
139 + 510611 = 510750

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 510,750 and was likely granted around 1893.

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