Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022988, here are decompositions:

  • 7 + 1022981 = 1022988
  • 11 + 1022977 = 1022988
  • 59 + 1022929 = 1022988
  • 89 + 1022899 = 1022988
  • 97 + 1022891 = 1022988
  • 107 + 1022881 = 1022988
  • 139 + 1022849 = 1022988
  • 151 + 1022837 = 1022988

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 2, 2988 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2988-02-01 (DMMYYYY (Euro, single-digit day))
  • 2988-10-02 (MMDYYYY (US, single-digit day))
  • 2988-02-10 (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 1,022,988 and was likely granted around 1912.

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