Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500390, here are decompositions:

73 + 500317 = 500390
103 + 500287 = 500390
151 + 500239 = 500390
157 + 500233 = 500390
181 + 500209 = 500390
193 + 500197 = 500390
211 + 500179 = 500390
223 + 500167 = 500390

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 500,390 and was likely granted around 1893.

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