Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023560, here are decompositions:

  • 3 + 1023557 = 1023560
  • 19 + 1023541 = 1023560
  • 61 + 1023499 = 1023560
  • 73 + 1023487 = 1023560
  • 151 + 1023409 = 1023560
  • 193 + 1023367 = 1023560
  • 199 + 1023361 = 1023560
  • 271 + 1023289 = 1023560

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 2, 3560 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 3560-02-01 (DMMYYYY (Euro, single-digit day))
  • 3560-10-02 (MMDYYYY (US, single-digit day))
  • 3560-02-10 (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 1,023,560 and was likely granted around 1912.

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