Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021928, here are decompositions:

31 + 1021897 = 1021928
67 + 1021861 = 1021928
79 + 1021849 = 1021928
97 + 1021831 = 1021928
151 + 1021777 = 1021928
181 + 1021747 = 1021928
277 + 1021651 = 1021928
307 + 1021621 = 1021928

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 2, 1928 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1928-02-01 (DMMYYYY (Euro, single-digit day))
1928-10-02 (MMDYYYY (US, single-digit day))
1928-02-10 (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 1,021,928 and was likely granted around 1912.

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