Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031930, here are decompositions:

7 + 1031923 = 1031930
19 + 1031911 = 1031930
61 + 1031869 = 1031930
199 + 1031731 = 1031930
223 + 1031707 = 1031930
307 + 1031623 = 1031930
337 + 1031593 = 1031930
397 + 1031533 = 1031930

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 3, 1930 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1930-03-01 (DMMYYYY (Euro, single-digit day))
1930-10-03 (MMDYYYY (US, single-digit day))
1930-03-10 (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 1,031,930 and was likely granted around 1912.

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