Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1010990, here are decompositions:

  • 7 + 1010983 = 1010990
  • 61 + 1010929 = 1010990
  • 73 + 1010917 = 1010990
  • 109 + 1010881 = 1010990
  • 157 + 1010833 = 1010990
  • 181 + 1010809 = 1010990
  • 193 + 1010797 = 1010990
  • 199 + 1010791 = 1010990

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 1, 0990 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 0990-10-01 (MMDYYYY (US, single-digit day))
  • 0990-01-10 (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 1,010,990 and was likely granted around 1911.

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