Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021732, here are decompositions:

59 + 1021673 = 1021732
71 + 1021661 = 1021732
191 + 1021541 = 1021732
269 + 1021463 = 1021732
359 + 1021373 = 1021732
401 + 1021331 = 1021732
431 + 1021301 = 1021732
443 + 1021289 = 1021732

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 2, 1732 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1732-02-01 (DMMYYYY (Euro, single-digit day))
1732-10-02 (MMDYYYY (US, single-digit day))
1732-02-10 (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 1,021,732 and was likely granted around 1912.

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