Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029988, here are decompositions:

5 + 1029983 = 1029988
59 + 1029929 = 1029988
107 + 1029881 = 1029988
149 + 1029839 = 1029988
257 + 1029731 = 1029988
419 + 1029569 = 1029988
461 + 1029527 = 1029988
467 + 1029521 = 1029988

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 2, 9988 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)

9988-02-01 (DMMYYYY (Euro, single-digit day))
9988-10-02 (MMDYYYY (US, single-digit day))
9988-02-10 (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 1,029,988 and was likely granted around 1912.

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