Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051728, here are decompositions:

11 + 1051717 = 1051728
19 + 1051709 = 1051728
31 + 1051697 = 1051728
79 + 1051649 = 1051728
89 + 1051639 = 1051728
107 + 1051621 = 1051728
109 + 1051619 = 1051728
127 + 1051601 = 1051728

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 5, 1728 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

1728-05-01 (DMMYYYY (Euro, single-digit day))
1728-10-05 (MMDYYYY (US, single-digit day))
1728-05-10 (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 1,051,728 and was likely granted around 1912.

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