Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020864, here are decompositions:

  • 11 + 1020853 = 1020864
  • 17 + 1020847 = 1020864
  • 23 + 1020841 = 1020864
  • 37 + 1020827 = 1020864
  • 41 + 1020823 = 1020864
  • 43 + 1020821 = 1020864
  • 67 + 1020797 = 1020864
  • 107 + 1020757 = 1020864

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 2, 0864 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0864-02-01 (DMMYYYY (Euro, single-digit day))
  • 0864-10-02 (MMDYYYY (US, single-digit day))
  • 0864-02-10 (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 1,020,864 and was likely granted around 1912.

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