Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039990, here are decompositions:

  • 11 + 1039979 = 1039990
  • 41 + 1039949 = 1039990
  • 47 + 1039943 = 1039990
  • 59 + 1039931 = 1039990
  • 89 + 1039901 = 1039990
  • 167 + 1039823 = 1039990
  • 173 + 1039817 = 1039990
  • 191 + 1039799 = 1039990

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 3, 9990 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 9990-03-01 (DMMYYYY (Euro, single-digit day))
  • 9990-10-03 (MMDYYYY (US, single-digit day))
  • 9990-03-10 (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 1,039,990 and was likely granted around 1912.

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