Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040990, here are decompositions:

31 + 1040959 = 1040990
43 + 1040947 = 1040990
61 + 1040929 = 1040990
109 + 1040881 = 1040990
157 + 1040833 = 1040990
163 + 1040827 = 1040990
193 + 1040797 = 1040990
211 + 1040779 = 1040990

Showing the first eight; more decompositions exist.

Other possible interpretations (3)

0990-04-01 (DMMYYYY (Euro, single-digit day))
0990-10-04 (MMDYYYY (US, single-digit day))
0990-04-10 (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 1,040,990 and was likely granted around 1912.

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