Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015000, here are decompositions:

11 + 1014989 = 1015000
47 + 1014953 = 1015000
59 + 1014941 = 1015000
113 + 1014887 = 1015000
131 + 1014869 = 1015000
137 + 1014863 = 1015000
167 + 1014833 = 1015000
179 + 1014821 = 1015000

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 1, 5000 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)

5000-10-01 (MMDYYYY (US, single-digit day))
5000-01-10 (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 1,015,000 and was likely granted around 1911.

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