Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1056666, here are decompositions:

  • 7 + 1056659 = 1056666
  • 43 + 1056623 = 1056666
  • 53 + 1056613 = 1056666
  • 67 + 1056599 = 1056666
  • 89 + 1056577 = 1056666
  • 97 + 1056569 = 1056666
  • 103 + 1056563 = 1056666
  • 157 + 1056509 = 1056666

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 5, 6666 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 6666-05-01 (DMMYYYY (Euro, single-digit day))
  • 6666-10-05 (MMDYYYY (US, single-digit day))
  • 6666-05-10 (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 1,056,666 and was likely granted around 1912.

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