Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000198, here are decompositions:

5 + 1000193 = 1000198
11 + 1000187 = 1000198
47 + 1000151 = 1000198
239 + 999959 = 1000198
281 + 999917 = 1000198
389 + 999809 = 1000198
449 + 999749 = 1000198
587 + 999611 = 1000198

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 1,000,198 and was likely granted around 1911.

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