Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045566, here are decompositions:

  • 7 + 1045559 = 1045566
  • 17 + 1045549 = 1045566
  • 19 + 1045547 = 1045566
  • 23 + 1045543 = 1045566
  • 37 + 1045529 = 1045566
  • 43 + 1045523 = 1045566
  • 59 + 1045507 = 1045566
  • 73 + 1045493 = 1045566

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 4, 5566 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 5566-04-01 (DMMYYYY (Euro, single-digit day))
  • 5566-10-04 (MMDYYYY (US, single-digit day))
  • 5566-04-10 (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 1,045,566 and was likely granted around 1912.

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