Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020920, here are decompositions:

  • 7 + 1020913 = 1020920
  • 13 + 1020907 = 1020920
  • 67 + 1020853 = 1020920
  • 73 + 1020847 = 1020920
  • 79 + 1020841 = 1020920
  • 97 + 1020823 = 1020920
  • 163 + 1020757 = 1020920
  • 211 + 1020709 = 1020920

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 2, 0920 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0920-02-01 (DMMYYYY (Euro, single-digit day))
  • 0920-10-02 (MMDYYYY (US, single-digit day))
  • 0920-02-10 (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 1,020,920 and was likely granted around 1912.

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