Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021958, here are decompositions:

61 + 1021897 = 1021958
79 + 1021879 = 1021958
97 + 1021861 = 1021958
109 + 1021849 = 1021958
127 + 1021831 = 1021958
151 + 1021807 = 1021958
181 + 1021777 = 1021958
199 + 1021759 = 1021958

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 1,021,958 and was likely granted around 1912.

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