Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505700, here are decompositions:

7 + 505693 = 505700
31 + 505669 = 505700
37 + 505663 = 505700
43 + 505657 = 505700
61 + 505639 = 505700
67 + 505633 = 505700
127 + 505573 = 505700
163 + 505537 = 505700

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 505,700 and was likely granted around 1893.

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