Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030400, here are decompositions:

31 + 1030369 = 1030400
43 + 1030357 = 1030400
103 + 1030297 = 1030400
109 + 1030291 = 1030400
181 + 1030219 = 1030400
199 + 1030201 = 1030400
331 + 1030069 = 1030400
367 + 1030033 = 1030400

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 3, 0400 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

0400-03-01 (DMMYYYY (Euro, single-digit day))
0400-10-03 (MMDYYYY (US, single-digit day))
0400-03-10 (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 1,030,400 and was likely granted around 1912.

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