Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028988, here are decompositions:

  • 7 + 1028981 = 1028988
  • 19 + 1028969 = 1028988
  • 31 + 1028957 = 1028988
  • 47 + 1028941 = 1028988
  • 151 + 1028837 = 1028988
  • 179 + 1028809 = 1028988
  • 211 + 1028777 = 1028988
  • 227 + 1028761 = 1028988

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 2, 8988 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 8988-02-01 (DMMYYYY (Euro, single-digit day))
  • 8988-10-02 (MMDYYYY (US, single-digit day))
  • 8988-02-10 (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 1,028,988 and was likely granted around 1912.

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