Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055880, here are decompositions:

  • 13 + 1055867 = 1055880
  • 17 + 1055863 = 1055880
  • 29 + 1055851 = 1055880
  • 41 + 1055839 = 1055880
  • 53 + 1055827 = 1055880
  • 71 + 1055809 = 1055880
  • 79 + 1055801 = 1055880
  • 97 + 1055783 = 1055880

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 5, 5880 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 5880-05-01 (DMMYYYY (Euro, single-digit day))
  • 5880-10-05 (MMDYYYY (US, single-digit day))
  • 5880-05-10 (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 1,055,880 and was likely granted around 1912.

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