Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018800, here are decompositions:

11 + 1018789 = 1018800
23 + 1018777 = 1018800
31 + 1018769 = 1018800
37 + 1018763 = 1018800
67 + 1018733 = 1018800
71 + 1018729 = 1018800
89 + 1018711 = 1018800
103 + 1018697 = 1018800

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 1, 8800 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)

8800-10-01 (MMDYYYY (US, single-digit day))
8800-01-10 (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 1,018,800 and was likely granted around 1911.

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