Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021688, here are decompositions:

37 + 1021651 = 1021688
61 + 1021627 = 1021688
67 + 1021621 = 1021688
127 + 1021561 = 1021688
271 + 1021417 = 1021688
307 + 1021381 = 1021688
397 + 1021291 = 1021688
601 + 1021087 = 1021688

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 1,021,688 and was likely granted around 1912.

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