Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013920, here are decompositions:

  • 29 + 1013891 = 1013920
  • 41 + 1013879 = 1013920
  • 101 + 1013819 = 1013920
  • 107 + 1013813 = 1013920
  • 179 + 1013741 = 1013920
  • 191 + 1013729 = 1013920
  • 233 + 1013687 = 1013920
  • 239 + 1013681 = 1013920

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 1, 3920 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 3920-10-01 (MMDYYYY (US, single-digit day))
  • 3920-01-10 (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 1,013,920 and was likely granted around 1911.

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