Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018906, here are decompositions:

3 + 1018903 = 1018906
17 + 1018889 = 1018906
47 + 1018859 = 1018906
89 + 1018817 = 1018906
137 + 1018769 = 1018906
173 + 1018733 = 1018906
197 + 1018709 = 1018906
227 + 1018679 = 1018906

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 1,018,906 and was likely granted around 1911.

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