Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510222, here are decompositions:

5 + 510217 = 510222
19 + 510203 = 510222
23 + 510199 = 510222
43 + 510179 = 510222
101 + 510121 = 510222
149 + 510073 = 510222
173 + 510049 = 510222
191 + 510031 = 510222

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 510,222 and was likely granted around 1893.

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