Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023240, here are decompositions:

11 + 1023229 = 1023240
13 + 1023227 = 1023240
19 + 1023221 = 1023240
37 + 1023203 = 1023240
41 + 1023199 = 1023240
67 + 1023173 = 1023240
73 + 1023167 = 1023240
107 + 1023133 = 1023240

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 2, 3240 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

3240-02-01 (DMMYYYY (Euro, single-digit day))
3240-10-02 (MMDYYYY (US, single-digit day))
3240-02-10 (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 1,023,240 and was likely granted around 1912.

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