Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040390, here are decompositions:

3 + 1040387 = 1040390
19 + 1040371 = 1040390
37 + 1040353 = 1040390
79 + 1040311 = 1040390
163 + 1040227 = 1040390
199 + 1040191 = 1040390
223 + 1040167 = 1040390
229 + 1040161 = 1040390

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 4, 0390 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

0390-04-01 (DMMYYYY (Euro, single-digit day))
0390-10-04 (MMDYYYY (US, single-digit day))
0390-04-10 (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 1,040,390 and was likely granted around 1912.

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