Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055500, here are decompositions:

11 + 1055489 = 1055500
29 + 1055471 = 1055500
71 + 1055429 = 1055500
101 + 1055399 = 1055500
113 + 1055387 = 1055500
137 + 1055363 = 1055500
179 + 1055321 = 1055500
197 + 1055303 = 1055500

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 5, 5500 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

5500-05-01 (DMMYYYY (Euro, single-digit day))
5500-10-05 (MMDYYYY (US, single-digit day))
5500-05-10 (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 1,055,500 and was likely granted around 1912.

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