Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011920, here are decompositions:

3 + 1011917 = 1011920
31 + 1011889 = 1011920
103 + 1011817 = 1011920
157 + 1011763 = 1011920
223 + 1011697 = 1011920
271 + 1011649 = 1011920
331 + 1011589 = 1011920
337 + 1011583 = 1011920

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 1, 1920 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)

1920-10-01 (MMDYYYY (US, single-digit day))
1920-01-10 (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 1,011,920 and was likely granted around 1911.

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