Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020828, here are decompositions:

  • 5 + 1020823 = 1020828
  • 7 + 1020821 = 1020828
  • 31 + 1020797 = 1020828
  • 71 + 1020757 = 1020828
  • 139 + 1020689 = 1020828
  • 197 + 1020631 = 1020828
  • 229 + 1020599 = 1020828
  • 239 + 1020589 = 1020828

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 2, 0828 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0828-02-01 (DMMYYYY (Euro, single-digit day))
  • 0828-10-02 (MMDYYYY (US, single-digit day))
  • 0828-02-10 (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 1,020,828 and was likely granted around 1911.

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