Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031400, here are decompositions:

43 + 1031357 = 1031400
53 + 1031347 = 1031400
101 + 1031299 = 1031400
109 + 1031291 = 1031400
211 + 1031189 = 1031400
239 + 1031161 = 1031400
263 + 1031137 = 1031400
281 + 1031119 = 1031400

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 3, 1400 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1400-03-01 (DMMYYYY (Euro, single-digit day))
1400-10-03 (MMDYYYY (US, single-digit day))
1400-03-10 (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 1,031,400 and was likely granted around 1912.

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