Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023400, here are decompositions:

11 + 1023389 = 1023400
47 + 1023353 = 1023400
71 + 1023329 = 1023400
83 + 1023317 = 1023400
89 + 1023311 = 1023400
101 + 1023299 = 1023400
137 + 1023263 = 1023400
173 + 1023227 = 1023400

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 2, 3400 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

3400-02-01 (DMMYYYY (Euro, single-digit day))
3400-10-02 (MMDYYYY (US, single-digit day))
3400-02-10 (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 1,023,400 and was likely granted around 1912.

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