Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015090, here are decompositions:

17 + 1015073 = 1015090
23 + 1015067 = 1015090
29 + 1015061 = 1015090
47 + 1015043 = 1015090
101 + 1014989 = 1015090
137 + 1014953 = 1015090
149 + 1014941 = 1015090
227 + 1014863 = 1015090

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 1, 5090 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)

5090-10-01 (MMDYYYY (US, single-digit day))
5090-01-10 (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 1,015,090 and was likely granted around 1911.

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