Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021564, here are decompositions:

3 + 1021561 = 1021564
23 + 1021541 = 1021564
101 + 1021463 = 1021564
107 + 1021457 = 1021564
191 + 1021373 = 1021564
197 + 1021367 = 1021564
233 + 1021331 = 1021564
263 + 1021301 = 1021564

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 2, 1564 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1564-02-01 (DMMYYYY (Euro, single-digit day))
1564-10-02 (MMDYYYY (US, single-digit day))
1564-02-10 (DDMYYYY (Euro, single-digit month))

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 1,021,564 and was likely granted around 1912.

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