Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018510, here are decompositions:

71 + 1018439 = 1018510
89 + 1018421 = 1018510
173 + 1018337 = 1018510
197 + 1018313 = 1018510
239 + 1018271 = 1018510
257 + 1018253 = 1018510
263 + 1018247 = 1018510
293 + 1018217 = 1018510

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 1,018,510 and was likely granted around 1911.

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