Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029620, here are decompositions:

  • 3 + 1029617 = 1029620
  • 19 + 1029601 = 1029620
  • 37 + 1029583 = 1029620
  • 43 + 1029577 = 1029620
  • 73 + 1029547 = 1029620
  • 103 + 1029517 = 1029620
  • 139 + 1029481 = 1029620
  • 211 + 1029409 = 1029620

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 2, 9620 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 9620-02-01 (DMMYYYY (Euro, single-digit day))
  • 9620-10-02 (MMDYYYY (US, single-digit day))
  • 9620-02-10 (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 1,029,620 and was likely granted around 1912.

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