Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027990, here are decompositions:

3 + 1027987 = 1027990
59 + 1027931 = 1027990
107 + 1027883 = 1027990
137 + 1027853 = 1027990
149 + 1027841 = 1027990
191 + 1027799 = 1027990
233 + 1027757 = 1027990
239 + 1027751 = 1027990

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 2, 7990 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

7990-02-01 (DMMYYYY (Euro, single-digit day))
7990-10-02 (MMDYYYY (US, single-digit day))
7990-02-10 (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 1,027,990 and was likely granted around 1912.

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