Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021648, here are decompositions:

71 + 1021577 = 1021648
107 + 1021541 = 1021648
191 + 1021457 = 1021648
281 + 1021367 = 1021648
317 + 1021331 = 1021648
347 + 1021301 = 1021648
359 + 1021289 = 1021648
389 + 1021259 = 1021648

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 1,021,648 and was likely granted around 1912.

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