Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028802, here are decompositions:

  • 29 + 1028773 = 1028802
  • 41 + 1028761 = 1028802
  • 53 + 1028749 = 1028802
  • 139 + 1028663 = 1028802
  • 223 + 1028579 = 1028802
  • 233 + 1028569 = 1028802
  • 241 + 1028561 = 1028802
  • 293 + 1028509 = 1028802

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 2, 8802 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 8802-02-01 (DMMYYYY (Euro, single-digit day))
  • 8802-10-02 (MMDYYYY (US, single-digit day))
  • 8802-02-10 (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 1,028,802 and was likely granted around 1912.

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