Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000218, here are decompositions:

5 + 1000213 = 1000218
7 + 1000211 = 1000218
19 + 1000199 = 1000218
31 + 1000187 = 1000218
47 + 1000171 = 1000218
59 + 1000159 = 1000218
67 + 1000151 = 1000218
97 + 1000121 = 1000218

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 1,000,218 and was likely granted around 1911.

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