Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021964, here are decompositions:

3 + 1021961 = 1021964
67 + 1021897 = 1021964
103 + 1021861 = 1021964
127 + 1021837 = 1021964
157 + 1021807 = 1021964
211 + 1021753 = 1021964
313 + 1021651 = 1021964
337 + 1021627 = 1021964

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 1,021,964 and was likely granted around 1912.

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