Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021012, here are decompositions:

11 + 1021001 = 1021012
23 + 1020989 = 1021012
53 + 1020959 = 1021012
131 + 1020881 = 1021012
173 + 1020839 = 1021012
191 + 1020821 = 1021012
233 + 1020779 = 1021012
269 + 1020743 = 1021012

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 1,021,012 and was likely granted around 1912.

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