Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048720, here are decompositions:

  • 3 + 1048717 = 1048720
  • 11 + 1048709 = 1048720
  • 17 + 1048703 = 1048720
  • 59 + 1048661 = 1048720
  • 107 + 1048613 = 1048720
  • 131 + 1048589 = 1048720
  • 137 + 1048583 = 1048720
  • 149 + 1048571 = 1048720

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 4, 8720 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 8720-04-01 (DMMYYYY (Euro, single-digit day))
  • 8720-10-04 (MMDYYYY (US, single-digit day))
  • 8720-04-10 (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 1,048,720 and was likely granted around 1912.

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