Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031402, here are decompositions:

3 + 1031399 = 1031402
79 + 1031323 = 1031402
103 + 1031299 = 1031402
241 + 1031161 = 1031402
283 + 1031119 = 1031402
349 + 1031053 = 1031402
409 + 1030993 = 1031402
571 + 1030831 = 1031402

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 3, 1402 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1402-03-01 (DMMYYYY (Euro, single-digit day))
1402-10-03 (MMDYYYY (US, single-digit day))
1402-03-10 (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 1,031,402 and was likely granted around 1912.

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