Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011290, here are decompositions:

13 + 1011277 = 1011290
19 + 1011271 = 1011290
61 + 1011229 = 1011290
73 + 1011217 = 1011290
127 + 1011163 = 1011290
151 + 1011139 = 1011290
199 + 1011091 = 1011290
211 + 1011079 = 1011290

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 1, 1290 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)

1290-10-01 (MMDYYYY (US, single-digit day))
1290-01-10 (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 1,011,290 and was likely granted around 1911.

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