Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505232, here are decompositions:

19 + 505213 = 505232
31 + 505201 = 505232
73 + 505159 = 505232
103 + 505129 = 505232
109 + 505123 = 505232
181 + 505051 = 505232
199 + 505033 = 505232
241 + 504991 = 505232

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 505,232 and was likely granted around 1893.

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