Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029628, here are decompositions:

  • 11 + 1029617 = 1029628
  • 59 + 1029569 = 1029628
  • 101 + 1029527 = 1029628
  • 107 + 1029521 = 1029628
  • 269 + 1029359 = 1029628
  • 419 + 1029209 = 1029628
  • 449 + 1029179 = 1029628
  • 461 + 1029167 = 1029628

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 2, 9628 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 9628-02-01 (DMMYYYY (Euro, single-digit day))
  • 9628-10-02 (MMDYYYY (US, single-digit day))
  • 9628-02-10 (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 1,029,628 and was likely granted around 1912.

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