Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500438, here are decompositions:

7 + 500431 = 500438
97 + 500341 = 500438
139 + 500299 = 500438
151 + 500287 = 500438
181 + 500257 = 500438
199 + 500239 = 500438
229 + 500209 = 500438
241 + 500197 = 500438

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 500,438 and was likely granted around 1893.

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