Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023512, here are decompositions:

  • 13 + 1023499 = 1023512
  • 103 + 1023409 = 1023512
  • 151 + 1023361 = 1023512
  • 199 + 1023313 = 1023512
  • 211 + 1023301 = 1023512
  • 223 + 1023289 = 1023512
  • 283 + 1023229 = 1023512
  • 313 + 1023199 = 1023512

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 2, 3512 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 3512-02-01 (DMMYYYY (Euro, single-digit day))
  • 3512-10-02 (MMDYYYY (US, single-digit day))
  • 3512-02-10 (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 1,023,512 and was likely granted around 1912.

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