Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021930, here are decompositions:

11 + 1021919 = 1021930
23 + 1021907 = 1021930
131 + 1021799 = 1021930
137 + 1021793 = 1021930
233 + 1021697 = 1021930
257 + 1021673 = 1021930
269 + 1021661 = 1021930
353 + 1021577 = 1021930

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 2, 1930 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1930-02-01 (DMMYYYY (Euro, single-digit day))
1930-10-02 (MMDYYYY (US, single-digit day))
1930-02-10 (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 1,021,930 and was likely granted around 1912.

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