Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026398, here are decompositions:

  • 7 + 1026391 = 1026398
  • 67 + 1026331 = 1026398
  • 181 + 1026217 = 1026398
  • 199 + 1026199 = 1026398
  • 271 + 1026127 = 1026398
  • 337 + 1026061 = 1026398
  • 367 + 1026031 = 1026398
  • 487 + 1025911 = 1026398

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 2, 6398 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 6398-02-01 (DMMYYYY (Euro, single-digit day))
  • 6398-10-02 (MMDYYYY (US, single-digit day))
  • 6398-02-10 (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 1,026,398 and was likely granted around 1912.

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