Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021346, here are decompositions:

13 + 1021333 = 1021346
19 + 1021327 = 1021346
43 + 1021303 = 1021346
103 + 1021243 = 1021346
163 + 1021183 = 1021346
223 + 1021123 = 1021346
349 + 1020997 = 1021346
367 + 1020979 = 1021346

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 1,021,346 and was likely granted around 1912.

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