Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500720, here are decompositions:

7 + 500713 = 500720
43 + 500677 = 500720
193 + 500527 = 500720
211 + 500509 = 500720
277 + 500443 = 500720
307 + 500413 = 500720
331 + 500389 = 500720
379 + 500341 = 500720

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 500,720 and was likely granted around 1893.

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