Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016990, here are decompositions:

  • 19 + 1016971 = 1016990
  • 31 + 1016959 = 1016990
  • 43 + 1016947 = 1016990
  • 61 + 1016929 = 1016990
  • 109 + 1016881 = 1016990
  • 151 + 1016839 = 1016990
  • 241 + 1016749 = 1016990
  • 349 + 1016641 = 1016990

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 1, 6990 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 6990-10-01 (MMDYYYY (US, single-digit day))
  • 6990-01-10 (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 1,016,990 and was likely granted around 1911.

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