Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1044720, here are decompositions:

23 + 1044697 = 1044720
31 + 1044689 = 1044720
67 + 1044653 = 1044720
101 + 1044619 = 1044720
107 + 1044613 = 1044720
137 + 1044583 = 1044720
151 + 1044569 = 1044720
191 + 1044529 = 1044720

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 4, 4720 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

4720-04-01 (DMMYYYY (Euro, single-digit day))
4720-10-04 (MMDYYYY (US, single-digit day))
4720-04-10 (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 1,044,720 and was likely granted around 1912.

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