Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040398, here are decompositions:

11 + 1040387 = 1040398
17 + 1040381 = 1040398
59 + 1040339 = 1040398
71 + 1040327 = 1040398
179 + 1040219 = 1040398
239 + 1040159 = 1040398
257 + 1040141 = 1040398
347 + 1040051 = 1040398

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 4, 0398 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

0398-04-01 (DMMYYYY (Euro, single-digit day))
0398-10-04 (MMDYYYY (US, single-digit day))
0398-04-10 (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 1,040,398 and was likely granted around 1912.

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